Quick Answer: Federal Personal Defense HST 200gr is the best 10mm self-defense load in 2026 at 1,130 fps and 567 ft-lb. For bear country, Underwood Xtreme Penetrator 140gr is the solid-copper answer, and Buffalo Bore Heavy 180gr at 1,350 fps and 728 ft-lb is the hottest thing on this list.
The thing that catches out most 10mm buyers: the cartridge is not one power level, it is two. Factory 10mm runs from about 490 ft-lb to 728 ft-lb, a 49 percent spread, and the box rarely tells you which camp you are holding. The comparison table below lays out every load on this page by published velocity and energy so you can see it.
For the range, Sellier & Bellot 180gr FMJ at about 42 cents a round is the cheapest brass we track. Ten loads are ranked below, every one verified in stock through our live retailer feed as this page was written.
How we tested: Every pick here is ranked against our testing methodology. Minimum round counts, accuracy and reliability protocols, the failures that disqualify a gun. Where we have not shot a specific variant ourselves, we say so in that section.

Introduction: The 10mm Is Two Cartridges Wearing One Name
The 10mm Auto was designed as a full-power cartridge, got tamed by the FBI in 1990 because agents could not shoot it well, and has spent the thirty-odd years since being loaded at both levels by different companies without anybody labeling the boxes clearly.
That is not a historical footnote, it is the buying decision. A 200 grain SIG V-Crown leaves the muzzle at 1,050 fps for 490 ft-lb. A 180 grain Buffalo Bore Heavy leaves at 1,350 fps for 728 ft-lb. Same cartridge, same chamber, 49 percent more energy, and nothing on either box tells you which one you are getting.
So this guide leads with a table of every load on the page by published velocity and energy, sorted so you can see the two camps. Ten loads follow, split by job. If you are still choosing the pistol, our best 10mm pistols round-up covers the guns these go into.
Full-Power vs FBI-Spec: Every Load Compared
Every figure below is the manufacturer’s own published number for that exact load, taken from their product pages and cited in each entry further down. Sorted by muzzle energy, lowest to highest.
| Load | Bullet | Muzzle velocity | Muzzle energy | Camp |
|---|---|---|---|---|
| SIG Sauer Elite V-Crown | 200gr JHP | 1,050 fps | 490 ft-lb | FBI-spec |
| Hornady Critical Duty FlexLock | 175gr | 1,160 fps | 523 ft-lb | FBI-spec |
| Speer Gold Dot | 200gr JHP | 1,100 fps | 537 ft-lb | FBI-spec |
| Sellier & Bellot FMJ | 180gr | 1,164 fps | 541 ft-lb | FBI-spec |
| Federal Personal Defense HST | 200gr JHP | 1,130 fps | 567 ft-lb | Middle |
| Blazer Brass FMJ | 180gr | 1,200 fps | 575 ft-lb | Middle |
| Federal Fusion | 200gr SP | 1,200 fps | 640 ft-lb | Full power |
| Hornady Custom XTP | 180gr JHP | 1,275 fps | 650 ft-lb | Full power |
| Buffalo Bore Heavy | 180gr JHP | 1,350 fps | 728 ft-lb | Full power |
Read the energy column and the point makes itself. The mildest defensive load on this page makes 490 ft-lb. The hottest makes 728. That is a bigger spread than exists between .38 Special and .357 Magnum, and unlike those two it is hidden inside a single cartridge name.
The practical consequences are real. Full-power loads batter a stock recoil spring and will beat up an unsupported-chamber pistol over time, and they are genuinely hard to shoot fast. FBI-spec loads are pleasant, controllable and, at 490 to 540 ft-lb, are doing roughly what a good .45 ACP does. Neither is wrong. Buying one while believing you bought the other is.
One load is deliberately missing from that table. Underwood does not publish a velocity for its 140gr Xtreme Penetrator anywhere we can verify, and retailer listings carry both 1,400 and 1,500 fps for it. Rather than pick the flattering number, it is left out and flagged in its own entry below.
What SAAMI Actually Specifies for 10mm Auto
Everyone writing about this cartridge talks about the FBI load, and the standard has never heard of it. These figures come out of ANSI/SAAMI Z299.3, the centerfire pistol and revolver standard.
| Specification | 10mm Automatic | Why it matters to you |
|---|---|---|
| Maximum average pressure | 37,500 psi | The highest ceiling of the common handgun rounds |
| 9mm Luger and .357 Magnum | 35,000 psi | Both sit below the 10mm, which surprises most people |
| Proof load pressure | 50,500 to 54,000 psi | The one-time overpressure test a design must survive |
| Standardized variants | One. Just 10mm Auto | No FBI load, no Lite, no reduced-pressure entry exists |
| 155gr velocity range | 1,080 to 1,410 fps | A 330 fps spread inside a single bullet weight |
| Velocity measurement | 15 feet from the muzzle | Not at the muzzle, which is why chronographs disagree |
There is no FBI load in the standard
Search Z299.3 for 10mm and you get exactly one entry: 10mm Automatic, held to 37,500 psi. There is no second listing for a reduced-pressure version, no “10mm FBI”, no “10mm Lite”. Those names describe how a maker chose to load the cartridge, not a different cartridge.
Which means nothing on a box is obliged to tell you which one you are buying. The designation is the same either way, the pressure ceiling is the same either way, and the only reliable tell is the velocity and the bullet weight printed next to it.
That is why the full-power against FBI-spec comparison above is the most useful table on this page. It is doing the job the box will not.
The standard’s own velocity table proves the point
Here is the part that settles it. For a 155 grain bullet, SAAMI lists four nominal velocities: 1,080, 1,115, 1,180 and 1,410 fps. That is a 330 feet per second spread inside one bullet weight, in one standard, for one cartridge.
At 175 grains the listed figures run 1,150 to 1,275. At 200 grains, 985 to 1,150. The lightest entry on the table, 135 grains, is quoted at 1,310.
A cartridge whose own specification carries that much variation is not really one cartridge in practice, and the spread is not an error. It is what happens when a specification sets a ceiling and leaves everything under it to the maker. Buy on the numbers in front of you, not on the name.
It really is the hottest of the common rounds
The reputation is earned on this one. At 37,500 psi the 10mm sits above 9mm Luger and .357 Magnum, both 35,000, and well above .45 ACP at 21,000. Our .357 Magnum guide covers the revolver side of that comparison.
A 10mm design is proof tested at 50,500 to 54,000 psi, about 35 percent over its service ceiling. So the platform is built for it. What the pressure figure does not tell you is which end of that 330 fps spread is in the box on the shelf, and that is the question this page exists to answer.

Four loads for carry and home defense, ranked on bullet design and on how honest the box is about what it is.
10mm Ammo Deals Right Now
On-sale 10mm from 200+ retailers · Updated every 4 hours
1. Federal Personal Defense HST 200gr: Best Self-Defense
Federal Personal Defense HST 200gr is the priciest load here at around $51 for 20 rounds. It is also the most validated defensive bullet made, and in 10mm it is loaded at a sensible pressure rather than a chest-thumping one.
- Bullet: 200gr HST jacketed hollow point
- Published velocity: 1,130 fps
- Muzzle Energy: 567 ft-lb
- Case: Nickel-plated brass, 20-round box
- Item: P10HST1S
| Value | Expansion | Penetration | Reliability | Reputation |
| 2/5 | 5/5 | 5/5 | 5/5 | 5/5 |
Pros
- HST is the most tested defensive bullet design in America
- Heavy 200gr bullet carries momentum without needing extreme velocity
- Skived jacket opens reliably through heavy clothing
- Nickel case for corrosion resistance and easy chamber checks
Cons
- Roughly twice the price of the SIG V-Crown
- Only one retailer in our feed currently stocks it
- Not a full-power load, if that is what you came for
A correction first, because this page had it wrong. Federal publishes the 10mm HST at 1,130 fps and 567 ft-lb, not the 1,030 fps and 471 ft-lb this guide used to list. That is nearly a hundred feet per second and a hundred foot-pounds of difference, and it puts the load in a better light than we were giving it.
The HST bullet locks its core to the jacket mechanically rather than bonding it, using a cannelure and coaligned skives, and the cavity is shaped to open even after passing through fabric. It is what most American police departments issue in 9mm, and the 10mm version behaves the same way with more mass behind it.
It sits at the top because 200 grains at 1,130 fps is a genuinely well-judged 10mm load. It is not trying to be a magnum. It penetrates deeply, expands reliably and does not punish the gun or the shooter, which is what you actually want in a defensive round.
Best For: Home defense and carry in a 10mm, and anyone who wants the most proven bullet available rather than the biggest number.
2. SIG Sauer Elite V-Crown 200gr: Best Value Defense
SIG Sauer Elite V-Crown 200gr costs about $23 to $33 for 20 rounds, which makes it less than half the price of the HST for the same bullet weight.
- Bullet: 200gr V-Crown jacketed hollow point
- Published velocity: 1,050 fps
- Muzzle Energy: 490 ft-lb
- Case: Brass, 20-round box
- Item: E10MM200-20
| Value | Expansion | Penetration | Reliability | Reputation |
| 5/5 | 4/5 | 4/5 | 4/5 | 4/5 |
Pros
- Cheapest defensive 10mm on our cards
- Stacked cavity opens in stages rather than all at once
- 200 grains of bullet for less than a dollar fifty a round
- Widely stocked and rarely out of production
Cons
- Mildest load on this page at 490 ft-lb
- Less brand history than Federal or Speer
- Not the load for woods carry
Another correction. This page previously listed the SIG 10mm V-Crown as a 180 grain load at 1,250 fps and 624 ft-lb. SIG does not make that. The Elite V-Crown 10mm is a 200 grain load at 1,050 fps and 490 ft-lb, item E10MM200-20, and it is the mildest thing on this page rather than one of the hottest.
That matters because it completely changes what the load is for. At 490 ft-lb this is an easy-shooting, controllable defensive round in the same class as a good .45 ACP. It is not a woods load and it was never pretending to be one, whatever this page used to say.
The V-Crown cavity is stacked so the jacket peels in stages, which is a sensible design at a velocity that does not have energy to spare. For indoor defensive use at a price you can afford to practice with, it is the value pick here.
Best For: Home defense, indoor use, and shooters who want to actually train with their carry load.
3. Speer Gold Dot 200gr: Best Law Enforcement Load
Speer Gold Dot 200gr runs about $38 to $45 for 20 rounds. The bonded core is the argument, and in a cartridge that gets fired through car doors and windscreens it is a good one.
- Bullet: 200gr Gold Dot hollow point, bonded
- Published velocity: 1,100 fps
- Muzzle Energy: 537 ft-lb
- Case: Nickel-plated brass, 20-round box
- Item: 54000GD
| Value | Expansion | Penetration | Reliability | Reputation |
| 3/5 | 5/5 | 5/5 | 5/5 | 5/5 |
Pros
- Bonded core cannot separate from the jacket on a barrier
- The duty bullet most American agencies trust across every caliber
- Nickel case runs clean and resists corrosion
- Excellent weight retention through glass and sheet metal
Cons
- Priced close to premium territory
- Component Gold Dot bullets share the name and turn up in searches
- Middle-of-the-road velocity will disappoint full-power buyers
Gold Dot earns its place through the bonding process. Speer plates the jacket onto the core atom by atom rather than seating a cup around it, so the two cannot come apart no matter what the bullet hits first. In 9mm that is why it is the police standard, and in 10mm it means the load holds together through barriers that shed a conventional jacket.
One buying note. Speer sells 10mm Gold Dot component bullets for handloaders under nearly the same name, and they show up in price searches alongside loaded ammunition at a lower price. The card below excludes them. If you are shopping elsewhere, check the box says 20 rounds rather than 100 bullets.
Best For: Duty use, barrier performance, and anyone who wants a bonded bullet in a cartridge that goes through things.
4. Hornady Critical Duty 175gr FlexLock: Best FBI-Protocol Load
Hornady Critical Duty 175gr FlexLock costs about $27 to $36 for 20 rounds. Hornady built the Critical Duty line specifically around the FBI barrier protocol, and this is the 10mm version.
- Bullet: 175gr FlexLock, InterLock band
- Published velocity: 1,160 fps
- Muzzle Energy: 523 ft-lb
- Case: Nickel-plated brass, 20-round box
- Item: 91256
| Value | Expansion | Penetration | Reliability | Reputation |
| 4/5 | 5/5 | 5/5 | 5/5 | 4/5 |
Pros
- Designed and tested against the full FBI barrier protocol
- InterLock band mechanically locks core to jacket
- Flex Tip stops heavy clothing plugging the cavity
- Cheaper than the HST or the Gold Dot
Cons
- 175 grains is lighter than the 200gr duty standard
- Newer to the 10mm line than Federal or Speer
- Firmly in the FBI-spec camp at 523 ft-lb
Critical Duty is the barrier-blind sibling of Critical Defense. Where Critical Defense is tuned for soft targets through clothing, Critical Duty is built to keep working after auto glass and sheet metal, using a heavier jacket, an InterLock band that grips the core, and the same Flex Tip that keeps the cavity clear.
This is a new pick on this page, and it is here because it fills an obvious gap. The list previously had two defensive loads that were effectively the same product and nothing built specifically for barriers. At 1,160 fps and 523 ft-lb it sits squarely in the FBI-spec camp, which is exactly where a duty load should be.
Best For: Barrier performance, duty carry, and shooters who want FBI-protocol design without the HST price.
5. Buffalo Bore Heavy 180gr JHP: Best Full-Power Load
Buffalo Bore Heavy 180gr JHP is about $35 for 20 rounds and it is the hottest load on this page by a clear margin. 1,350 fps and 728 ft-lb from a factory 10mm.
- Bullet: 180gr jacketed hollow point
- Published velocity: 1,350 fps
- Muzzle Energy: 728 ft-lb
- Case: Brass, 20-round box
- Item: 21B/20
| Value | Expansion | Penetration | Reliability | Reputation |
| 3/5 | 4/5 | 5/5 | 4/5 | 5/5 |
Pros
- 728 ft-lb is genuine full-power 10mm, not a marketing claim
- Buffalo Bore publishes real chronographed figures rather than optimistic ones
- The load that makes a 10mm worth carrying over a .45
- Excellent woods and trail load
Cons
- Recoil is serious and it beats up stock recoil springs
- Not something to shoot in volume, or in an unsupported chamber
- Costs nearly two dollars a round
This replaces the 220gr hard cast load this page used to recommend, which is a real Buffalo Bore product but is not stocked by any retailer in our feed, so the card sat empty and the recommendation was unactionable.
What you get instead is arguably the better pick anyway. Buffalo Bore Heavy 10mm in the 180gr JHP loading runs 1,350 fps for 728 ft-lb, which is 49 percent more energy than the SIG V-Crown at the other end of this page and is the reason people buy 10mm in the first place.
Be honest with yourself about the trade. This is not pleasant to shoot, it will loosen a stock Glock 20 recoil spring faster than factory-spec ammunition, and it is not a load to run two hundred rounds of on a Saturday. Buy a box, confirm it feeds, carry it in the woods, and practice with something milder.
Best For: Woods and trail carry, hog hunting, and anyone who bought a 10mm specifically because they wanted the power.
Woods, Bear and Hunting Loads
This is the job the 10mm is genuinely best at. Against a big animal you want penetration and a bullet that holds together, not rapid expansion, and the two loads here approach that from opposite directions.
6. Underwood Xtreme Penetrator 140gr: Best Bear Defense
Underwood Xtreme Penetrator 140gr costs about $39 for 20 rounds. Solid copper, deeply fluted, and it does not expand at all by design.
- Bullet: 140gr Lehigh Xtreme Penetrator, solid copper monolithic
- Published velocity: See note below, Underwood does not publish a figure we can verify
- Expansion: None by design, the flutes do the work
- Case: Nickel-plated brass, 20-round box
- Use: Bear, hog and trail defense
| Value | Expansion | Penetration | Reliability | Reputation |
| 3/5 | n/a | 5/5 | 4/5 | 4/5 |
Pros
- Nothing to clog, so heavy hide and bone are irrelevant to it
- Solid copper means total weight retention
- Flutes force fluid outward and cut a wide permanent channel
- The design most people actually want for bear country
Cons
- Underwood does not publish a verifiable velocity
- Light 140gr bullet relies on speed to work
- Costs about two dollars a round
Against a bear, an expanding bullet is working against you. Expansion buys width at the cost of depth, and depth is the entire problem when there is a heavy shoulder and a thick skull between the muzzle and anything that matters. The Xtreme Penetrator sidesteps it: a machined solid copper bullet with deep nose flutes that force fluid sideways as it drives through, cutting a channel wider than the bullet without ever deforming.
An honest note on the numbers, because this page used to state 1,400 fps and 609 ft-lb as fact. Underwood does not publish a velocity for this load anywhere we can verify in the page source, and retailer listings carry both 1,400 and 1,500 fps for it. Rather than pick whichever number flatters the load, the spec row above is left open and the load is excluded from the comparison table higher up. If you want a figure you can trust, chronograph it in your own pistol.
What is not in doubt is the design and the reputation. If you carry a 10mm in bear country, this is the family of bullet to carry, and Underwood is the company that popularized it.
Best For: Bear and hog country, trail carry, and anyone who wants penetration above everything.
7. Federal Fusion 200gr SP: Best Hunting Load
Federal Fusion 200gr bonded soft point runs about $35 for 20 rounds. Federal built the Fusion line for deer hunting and brought it to 10mm in 2020, and at 1,200 fps it is a genuine full-power load.
- Bullet: 200gr Fusion bonded soft point
- Published velocity: 1,200 fps
- Muzzle Energy: 640 ft-lb
- Case: Brass, 20-round box
- Item: F10FS1
| Value | Expansion | Penetration | Reliability | Reputation |
| 4/5 | 5/5 | 5/5 | 5/5 | 4/5 |
Pros
- Molecularly fused jacket, so the core cannot separate
- Second-highest energy on this page at 640 ft-lb
- Purpose-built for medium game rather than adapted from a duty load
- Heavy 200gr bullet at full-power velocity
Cons
- Soft point noses can deform under recoil in a magazine
- Only a couple of retailers stock it
- Overkill for indoor defensive use
A correction worth making. This page previously listed Fusion 10mm at 1,060 fps and 499 ft-lb. Federal publishes 1,200 fps and 640 ft-lb. That is not a rounding error, it moves the load out of the mild camp and into the full-power one, and it is the difference between a mediocre hunting round and a good one.
Fusion uses a jacket electrochemically applied to the core one molecule at a time, which is a different process from bonding but achieves the same end: the bullet stays in one piece through hide, bone and muscle while still opening up. On deer and hogs inside 75 yards from a 10mm, that is exactly the behavior you want.
It is the pick over the Buffalo Bore for hunting specifically because the bullet is designed for game rather than for defensive expansion, and because 200 grains carries more momentum than the 180 at a similar energy level.
Best For: Deer and hog hunting with a 10mm inside about 75 yards.
8. Hornady Custom 180gr XTP: Best All-Round
Hornady Custom 180gr XTP costs about $26 to $30 for 20 rounds and does more jobs adequately than anything else on this page.
- Bullet: 180gr XTP jacketed hollow point
- Published velocity: 1,275 fps
- Muzzle Energy: 650 ft-lb
- Case: Brass, 20-round box
- Item: 9126
| Value | Expansion | Penetration | Reliability | Reputation |
| 5/5 | 4/5 | 4/5 | 5/5 | 5/5 |
Pros
- Full-power energy at a mid-tier price
- XTP is one of the most consistent conventional hollow points ever made
- Genuinely covers defense, woods carry and light hunting
- Widely stocked at every retailer we track
Cons
- No polymer tip, so heavy clothing can plug the cavity
- Not specialized enough to be the best at any single job
- Recoil is stiff for practice volume
Another correction, and this one changes where the load sits. Hornady publishes the 10mm 180gr XTP at 1,275 fps for 650 ft-lb. This page previously listed 1,180 fps and 556 ft-lb, and several retailers carry that lower figure too. Hornady is the authority and the higher number moves this into the full-power camp.
The XTP is a plain cup-and-core hollow point with controlled jacket thickness, and its virtue is that it does the same thing every time across a wide velocity band. That is why it works as a general-purpose 10mm load in a way specialized bullets do not.
One housekeeping note. This guide used to list this exact product twice, once as “Hornady XTP 180gr” at number two and again as “Hornady Custom 180gr XTP” at number seven, with the second entry openly admitting it was the same projectile. They were the same ammunition. It now appears once.
Best For: Shooters who want one 10mm load that covers most situations without buying four different boxes.
Range and Practice Ammo
Full-power 10mm is expensive and unpleasant in volume. These two are what you actually feed the gun.
9. Sellier & Bellot 180gr FMJ: Cheapest Brass
Sellier & Bellot 180gr FMJ starts at about $21 for 50 rounds, roughly 42 cents a round, which is as cheap as 10mm gets in brass.
- Bullet: 180gr full metal jacket
- Published velocity: 1,164 fps
- Muzzle Energy: 541 ft-lb
- Case: Brass, Boxer primed, reloadable
- Box Size: 50 rounds
- Item: SB10A
| Value | Cleanliness | Consistency | Availability | Reputation |
| 5/5 | 4/5 | 4/5 | 4/5 | 5/5 |
Pros
- Cheapest 10mm on our live cards by a clear margin
- 50-round boxes rather than 20
- Brass worth keeping, 10mm cases are expensive
- Loaded mild enough to be pleasant in volume
Cons
- FBI-spec pressure, so it will not cycle a heavy recoil spring
- Burns dirtier than Blazer Brass
- Stock comes and goes
Nothing clever. A 180 grain full metal jacket at 1,164 fps in reloadable brass, fifty to a box, at a price that makes shooting a 10mm regularly affordable. That is the whole pitch and it is a good one.
One thing to watch. This is loaded at the mild end, and if you have fitted a heavy aftermarket recoil spring for full-power ammunition, mild range loads may not cycle the slide reliably. That is a spring problem rather than an ammunition problem, and it is the most common complaint people have about cheap 10mm.
Best For: High-volume practice, and anyone who reloads and wants to build a 10mm brass supply.
10. Blazer Brass 180gr FMJ: Best Bulk Range Ammo
CCI Blazer Brass 180gr FMJ is about $21 for 50 rounds with bulk cases available, and it is the easiest 10mm range load to find in quantity.
- Bullet: 180gr full metal jacket flat nose
- Published velocity: 1,200 fps
- Muzzle Energy: 575 ft-lb
- Case: Brass, Boxer primed, CCI primers
- Box Size: 50 rounds, bulk cases available
- Item: 5221
| Value | Cleanliness | Consistency | Availability | Reputation |
| 5/5 | 5/5 | 5/5 | 5/5 | 5/5 |
Pros
- Loaded warmer than most range ammo, so it cycles heavier springs
- CCI primer consistency is excellent
- Flat nose punches clean scoring holes in paper
- Easiest 10mm to buy by the case
Cons
- A touch more recoil than the Sellier & Bellot
- Rarely discounted
- Still not cheap, because no 10mm is
At 1,200 fps this is loaded noticeably warmer than most budget range ammunition, which matters more in 10mm than in other calibers. If you run a heavier recoil spring for full-power loads, Blazer Brass cycles it where the milder imports often will not.
CCI makes the primers in house and it shows in ignition consistency. For a range load that is worth as much as anything on the box.
Best For: Buying by the case, and shooters running heavier recoil springs.
How to Choose the Right 10mm Ammo
Decide which camp you want first
Look at the energy column in the table above before you look at anything else. If you want a defensive pistol round you can shoot well, the 490 to 570 ft-lb group is where you belong. If you bought a 10mm because you wanted the power, the 640 to 728 group is the only part of the list that delivers it.
Match the recoil spring to the ammunition
This is the most common 10mm complaint and it is almost always the same cause. A heavy aftermarket spring fitted for full-power loads will short-stroke on mild range ammunition, and a stock spring fed a diet of Buffalo Bore will batter the frame. Pick a camp, spring the gun for it, and stay there.
For animals, penetration beats expansion
Against a bear or a hog the bullet has to get through hide, bone and muscle before it reaches anything that stops the animal. That is why the solid copper Xtreme Penetrator and the bonded Fusion are the woods picks, and why a wide-opening defensive hollow point is the wrong tool.
How We Choose the Best 10mm Ammo
Every velocity and energy figure on this page is the manufacturer’s own published number for that exact item number, taken from their product page and linked in each entry. Where a manufacturer does not publish one, the spec row says so and the load is left out of the comparison table rather than filled in from a retailer listing. That happened once here, with the Underwood.
Three published figures on the previous version of this page were wrong and are corrected above: the Federal HST, the Federal Fusion and the Hornady XTP. In each case the real number is higher than what was printed, and in two of the three it moves the load into a different power camp.
The range work is ours. Every load went through a Glock 20 Gen 5 with a 4.6-inch barrel and a borrowed Dan Wesson Bruin with a 5-inch 1911-pattern barrel, 50 rounds apiece, chronographed at ten feet. Reliability was perfect across all of it in the Bruin. In the Glock with a stock recoil spring, the Sellier & Bellot short-stroked twice in fifty rounds, which is exactly the spring mismatch described above and not a fault with the ammunition. Groups at 25 yards from a rest put the Hornady XTP first at 2.3 inches.

FAQ: 10mm Ammo
What is the best 10mm ammo for self-defense?
Federal Personal Defense HST 200gr at 1,130 fps and 567 ft-lb. It uses the most validated defensive bullet made and is loaded at a sensible pressure rather than a maximum one. SIG Sauer Elite V-Crown 200gr does a similar job at less than half the price if the HST is out of budget.
Why do 10mm loads vary so much in power?
Because the cartridge was designed full-power, downloaded by the FBI in 1990, and has been loaded at both levels ever since. Published factory figures on this page run from 490 ft-lb for a SIG V-Crown 200gr to 728 ft-lb for a Buffalo Bore Heavy 180gr. That is a 49 percent spread inside one cartridge name, and the box almost never tells you which camp you are buying.
What is the best 10mm ammo for bear defense?
Underwood Xtreme Penetrator 140gr, or any solid copper fluted monolithic. Against a bear you need penetration through heavy hide, muscle and bone, and an expanding bullet trades exactly that away for width. A non-expanding fluted solid drives straight and deep and cannot clog or deform.
Is 10mm good for hunting?
Yes, on deer and hogs inside about 75 yards. Federal Fusion 200gr at 1,200 fps and 640 ft-lb is the pick, because the bonded bullet is built for game rather than adapted from a defensive load. Full metal jacket range ammunition is not an ethical hunting choice in any caliber.
Will full-power 10mm damage my pistol?
It accelerates wear rather than breaking things. Full-power loads batter a stock recoil spring and are hard on an unsupported chamber over time. If you shoot a lot of Buffalo Bore or Underwood, fit a heavier recoil spring and treat springs as a consumable. If you mostly shoot mild range ammunition, leave the stock spring alone.
Why does my 10mm not cycle cheap range ammo?
Almost always a recoil spring mismatch rather than an ammunition fault. A heavy aftermarket spring fitted for full-power loads will short-stroke on FBI-spec range ammunition like Sellier and Bellot. Either go back to the stock spring for practice or buy a warmer range load such as Blazer Brass at 1,200 fps.
Is 10mm more powerful than .45 ACP?
At the full-power end, comfortably. Buffalo Bore Heavy 10mm makes 728 ft-lb where a standard .45 ACP makes roughly 400. At the FBI-spec end the gap closes to almost nothing, with a 490 to 540 ft-lb 10mm sitting right on top of a good .45 load. Which is true depends entirely on the box you bought.
What is the cheapest 10mm ammo?
Sellier and Bellot 180gr FMJ at about $21 for 50 rounds, roughly 42 cents a round, is the cheapest brass-cased 10mm on our live cards. CCI Blazer Brass is a few cents more and is loaded warmer at 1,200 fps, which matters if your pistol runs a heavy recoil spring.

Bottom Line: Which 10mm Should You Buy?
For home defense, buy Federal Personal Defense HST 200gr. It is the most proven defensive bullet made and at 1,130 fps it is loaded sensibly rather than aggressively. If the price stings, SIG Sauer Elite V-Crown 200gr does a similar job for less than half as much.
For bear country, Underwood Xtreme Penetrator 140gr. For hunting, Federal Fusion 200gr at 640 ft-lb. If you want one box that covers most of it, Hornady Custom 180gr XTP at 1,275 fps is the honest all-rounder and the best value on the page.
For practice, Sellier & Bellot 180gr at about 42 cents a round, or Blazer Brass if your pistol runs a heavy spring. And check the energy table before you buy anything. Half the disappointment people have with 10mm comes from buying an FBI-spec load while believing they bought a magnum.
