Yes, 8mm Mauser ammo is still made, and there’s more of it on dealer shelves than most people expect. Federal, Winchester, Hornady, Prvi Partizan, Sellier & Bellot, Norma, Nosler and Buffalo Bore all load it. On the day we checked, the dealers on our price cards had more than 60 different listings in stock, and a box of 20 new brass-cased rounds started at under $27.

The catch is that “8mm Mauser” on a box tells you less than you’d think. An American box and a European box can sit side by side on the same shelf and differ by more than 800 foot-pounds at the muzzle, because the US pressure limit for this cartridge is lower than the one for the .30-30.

Some old rifles should never see the hot one. Most are fine with it. And a few boxes that show up under the 8mm Mauser name won’t chamber in your rifle at all. This guide sorts out who makes what, what it costs per round, and which load belongs in which old rifle.

Who Still Makes 8mm Mauser Ammo in 2026

At least ten companies load 8mm Mauser ammo in 2026: Federal, Winchester, Hornady, Prvi Partizan, Sellier & Bellot, Norma, Nosler, Buffalo Bore, RWS and Lapua. Three of them sell it under the 8mm Mauser name and the rest call it 8×57 JS.

More companies than you’d guess. We went to each maker’s own product pages on October 1, 2026 and wrote down what they list. The velocity column is the maker’s own number. Where a European maker publishes meters per second, we’ve converted it, so treat those as close rather than exact.

A few notes on that table. Nosler loads a 180-grain E-Tip and a 180-grain Ballistic Tip in 8×57 JS, and our dealers stock both, but we couldn’t confirm a current velocity from Nosler for either. HSM’s 175-grain load is on our dealers’ shelves too. Remington’s Core-Lokt page had no 8mm Mauser entry on the day we looked, and we couldn’t find a statement from Remington either way, so we’ve left it out.

The one that throws people is Prvi Partizan. PPU is made in Serbia, so shooters assume it’s hot European ammo. The boxes sold here under the “8mm Mauser” name aren’t. PPU lists its 198-grain FMJ at 665 meters per second, about 2,180 fps, which is slower than the old military load by about 300 fps.

PPU does make a full-power line, and it sells it under the “8 x 57 IS” name with the same bullets at about 2,430 fps. If full power matters to you, read the velocity on the box and ignore the country of origin.

What 8mm Mauser Ammo Costs in 2026

New 8mm Mauser ammo costs about $1.32 to $1.90 a round for brass-cased FMJ and soft points from Prvi Partizan and Sellier & Bellot, and $2.75 to $3.50 a round for Federal’s American load, going by dealer listings on October 1, 2026.

We pulled every 8mm Mauser listing from the dealers on our cards on October 1, 2026 and sorted them by type. Prices are for a box of 20 unless noted, and they move, so use the live cards for today’s number.

Read that table twice, because it’s upside down from what you’d expect. The weakest load in the caliber, Federal’s 170-grain soft point, costs about double what Sellier & Bellot’s full-power hunting load costs, and well over the Norma. You’re paying for a low-volume American production run. For a sound military Mauser, the European boxes are the better buy.

How does it compare with other rifle rounds? It costs more. On the same day, 150-grain .30-06 started at $21.99 a box on our cards. The gap comes down to volume: nobody makes 8mm Mauser in the quantities that .308 and .30-06 are made in.

For the wider market, our ammo price report tracks what the common calibers cost.

Surplus is the other option. Our dealers didn’t have any military surplus 8mm in stock when we checked, but dedicated surplus sellers do, mostly Romanian steel-case from the 1970s in sealed tins, at roughly 70 to 80 cents a round. It’s cheaper, it’s corrosive, and it comes with rules. We cover those below.

What’s Safe in Your Rifle

Any current .323 factory load is safe in a sound Karabiner 98k, Gewehr 98, vz. 24 or Yugoslav M48, while a Gewehr 88 or an old German sporting rifle needs a gunsmith’s inspection before it fires anything.

This is the part no ammo listing tells you. Find your rifle in the table.

“Mild US load” means the 170-grain Federal or Winchester and PPU’s “8 mm Mauser” line. “Full power” means Norma, Sellier & Bellot, Hornady Vintage Match and the like. Every row assumes a gunsmith has checked the rifle’s headspace and condition, which any 80-year-old military rifle deserves before its first shot.

Two things in that table do most of the work. First, a 98-pattern military Mauser in good condition is a strong rifle built around the full-power cartridge, so the European loads are what it was designed to shoot.

Second, the semi-autos are fussier than the bolt guns. The Hakim and the FN-49 both have gas systems that are adjusted with a special tool, so the rifle has to be set up for the load you feed it. If you don’t know how yours is set, have a gunsmith check it before you change ammunition.

Forgotten Weapons tested 1940s Turkish surplus at 2,948 fps from a K98k, called it “definitely overpressure” and warned against using it in any self-loading rifle. We’d follow that.

Don’t have the rifle yet? These are the surplus rifles in 8mm Mauser our dealers have right now. Our Mauser rifle buyer’s guide covers which ones to buy, and the best military surplus rifles roundup compares them with the rest.

Why American 8mm Mauser Is Loaded So Light

American 8mm Mauser ammo is loaded light because SAAMI caps the cartridge at a maximum average pressure of 35,000 psi, while Europe’s C.I.P. allows the same round 3,900 bar, about 56,500 psi.

There are two rulebooks for this cartridge. In the US, SAAMI sets the maximum average pressure for 8mm Mauser at 35,000 psi. In Europe, C.I.P. sets the limit for the same cartridge, which it calls 8 x 57 IS, at 3,900 bar. That’s about 56,500 psi, roughly 60 percent higher.

You can read both for yourself in the SAAMI centerfire rifle standard and the C.I.P. data sheet.

To see how low the American number is, line it up against other cartridges in the same SAAMI table:

A cartridge that armed Germany through World War I and World War II is held below the .30-30. SAAMI does not publish its reasons, but gun writers give two. American Hunter blames “older rifles, whose metallurgy may not be capable of handling higher pressures.” Others point to the bore mix-up we cover next: if someone fires a modern .323 bullet through an old .318 barrel, a low-pressure load gives them a margin.

The result is on the box. SAAMI’s reference load is a 170-grain bullet at 2,340 fps, and Federal lists its 170-grain Power-Shok at 2,250 fps and 1,911 foot-pounds. For comparison, Federal’s own 180-grain .308 load makes 2,640 foot-pounds and its 180-grain .30-06 makes 2,913.

In American trim, the 8mm Mauser is a .32 Special. In European trim, with a 196-grain bullet at about 2,525 fps, it makes close to 2,780 foot-pounds and sits between the .308 and the .30-06.

That doesn’t make the mild load bad. It’s easy on an old rifle and easy on your shoulder, and at woods ranges a 170-grain soft point at 2,250 fps kills deer the same way a .30-30 always has. It’s just a different tool from the box next to it.

J Bore vs. S Bore: .318 or .323

8mm Mauser rifles come in two bore sizes: the original 1888 J bore takes a .318-inch bullet, and the S bore, standard on military rifles since 1905, takes the .323-inch bullet that every current factory load uses.

Here’s the one mix-up in this caliber that can hurt you. The original 1888 cartridge, made for the Gewehr 88 “Commission rifle,” used a round-nosed bullet .318 inches across. In 1903 Germany designed a new pointed bullet .323 inches across, the S cartridge, and by 1905 it was the service round. Every military Mauser built for it since has the larger bore.

The letters come from that history. The “I” stands for Infanterie, and the “J” you see on most boxes is the same letter misread. The “S” stands for Spitzgeschoss, pointed bullet, and today it marks the .323 bore.

So 8×57 JS and 8×57 IS are the same round, and it’s the one everybody means by 8mm Mauser. Plain 8×57 J, with no S, is the old .318 round.

And no, Paul Mauser didn’t design the cartridge. A German army commission did, and the Mauser name stuck later because of the Gewehr 98.

The rule comes from the NRA’s Shooting Sports USA: “it is not safe to fire the 8×57 mm Mauser ammunition with .323″ diameter bullets in rifles having .318″ diameter bores.” A fat bullet in a tight barrel means dangerous pressure. All current American factory ammunition and nearly all surplus is .323.

Which rifles are the risk?

• Gewehr 88 Commission rifles. Many were converted for the S cartridge and stamped with an “S” on the receiver. Shooting Sports USA says not to fire even the S-marked ones. We wouldn’t shoot one without a gunsmith’s say-so.
• Pre-war German sporting rifles, drillings and combination guns. These can be .318 or .323, and many are chambered for the rimmed versions. Nothing on the outside tells you for sure.
• Any rifle you can’t identify. If the markings are gone or the rifle has been rebarreled, treat it as unknown.

What to do is simple. Take the rifle to a gunsmith and ask for the bore to be slugged and the chamber checked. Slugging means driving a soft lead slug through the barrel and measuring it.

Ask for both, because groove diameter on its own doesn’t settle it: some later Gewehr 88 barrels were cut with deeper grooves while the chamber stayed the old size. Ammunition with true .318 bullets is a specialty item, so if your rifle turns out to be a J bore, that’s a conversation to have with the gunsmith too.

8×57 JS, 7.92×57 and the Names That Look Right but Aren’t

Boxes marked 7.92×57 ammo, 8×57 JS, 8×57 IS and 8mm Mauser all hold the same cartridge. The trouble starts with the names that sit next to them.

Ammo feeds and store shelves file several different cartridges under “8mm.” One forum poster described being handed a box of 8×57 JRS over a gun-store counter when he asked for 8mm Mauser. Here’s the full list of what fits a standard 8mm Mauser bolt rifle and what doesn’t.

The rimmed JRS is the one that catches buyers, because it’s cheap and it sits in the same search results. That’s why the cards on this page filter it out. If you own a drilling or a single-shot stalking rifle marked 8×57 JRS, it’s the right round for you, and the card below is the only one on this page you want.

8mm Mauser Surplus Ammo: What’s Worth Buying

8mm Mauser surplus ammo is corrosive, Berdan primed and cheaper than new production, at roughly 70 to 80 cents a round for 1970s Romanian steel-case against about $1.32 for new brass-cased FMJ.

For decades surplus was how people fed these rifles, and some of it is still around. Treat all of it as corrosive unless the seller can prove otherwise, and expect it to be Berdan primed, which means the cases aren’t practical to reload. Here’s what’s documented about the common types.

Turkish surplus has a reputation, and it’s partly earned. It’s 80-year-old ammunition loaded warm. Firearms News shot 1940 Turkish ball in a K98k in 2026 and got its best groups of the test at 2,877 fps, so a good lot can shoot very well.

A bad lot gives you hangfires. Keep it to sound 98-pattern bolt-action rifles and out of anything semi-automatic.

If you get a hangfire

A hangfire is a delay between the firing pin falling and the round going off. If you pull the trigger and get a click, keep the rifle on your shoulder with the muzzle pointed downrange and wait. The NRA’s range safety guidance says at least 60 seconds before opening the action. The delay with old surplus can be longer than you’d think, and a round that fires with the bolt half open is how people get hurt.

Cleaning after corrosive ammo

A corrosive primer leaves potassium chloride and sodium chloride in the bore, salts that pull moisture out of the air and rust the steel. Ordinary solvent will not dissolve them. Water does. Clean the same day:

1. Flush the bore from the chamber end with hot water, or wet patches with an ammonia-based window cleaner.
2. Do the same to the bolt face. On a Hakim, FN-49 or G43, do the gas system and bolt carrier too.
3. Dry everything with clean patches.
4. Clean the normal way with a brush and bore solvent.
5. Oil all the metal, and check the bore again the next day.

If that sounds like a chore, it’s the best argument for new ammunition. PPU says its commercial primers are non-corrosive, and Hornady built Vintage Match as a modern stand-in for military ball.

8mm Mauser for Hunting

With a European 196-grain soft point at about 2,525 fps and 2,775 foot-pounds, the 8mm Mauser is a full big game cartridge, and Gun Digest calls it adequate for any North American big game with the proper bullets and full loadings.

In Europe this is still an everyday hunting round, and with the right box it’ll do anything a .30-06 will. Gun Digest puts it this way: as loaded by Norma and the other European companies, “it’s in the same class as our .30-06.” The catch, again, is which box.

For whitetails inside 150 yards, the American 170-grain load is plenty, and the light recoil is a bonus in a steel-buttplate military rifle. For elk, hogs, black bear or longer shots, use a European 196-grain soft point or a premium load. Norma’s Whitetail is the easy pick, since it’s widely stocked and costs less than the Federal. Never hunt with FMJ, surplus or otherwise.

Is it better than a .308? With a European load it carries a heavier bullet and a little more energy than Federal’s 180-grain .308. With the American load it gives up more than 700 foot-pounds to it.

Recoil follows the power. Chuck Hawks’ recoil table puts a 170-grain load at 2,400 fps in an eight-pound rifle at about 13.6 foot-pounds, against 18.5 for a 195-grain load at 2,500 fps and 20.3 for a 180-grain .30-06. Our guide to the best deer hunting cartridges puts those numbers in context, and if you’re weighing an old Mauser against a modern rifle, our .30-06 guide is the fair comparison.

8mm Mauser Myths vs. the Truth

These are the claims that come up most on the forums, and where the evidence lands on each.

Our Range Notes: Five Loads in a Yugo M48

We took a Yugoslav M48 with a bright bore and a chronograph to the range for two mornings in September and shot 180 rounds: four commercial loads and one tin of 1970s Romanian surplus. Groups were five shots at 100 yards from a rest with the issue sights.

The chronograph backed up the makers. The PPU and the Federal were soft, pleasant loads, and the M48’s steel buttplate wasn’t a problem with either. The Sellier & Bellot was a different rifle: sharper recoil and a lot more blast. That’s the cartridge the M48 was built for.

The Hornady shot the best groups by a clear margin, which is what a match bullet should do.

We had no misfires with any commercial load. The Romanian surplus fired every time too, but it was the least accurate ammunition of the day and the dirtiest, and it meant a water flush of the bore and bolt before we left the range. With the battle sight on its lowest setting, every load printed high at 100 yards, the heavy bullets by the most, so plan on holding low or installing a taller front sight.

If we were stocking up for this rifle, we’d buy PPU for casual range days, Sellier & Bellot or Norma for hunting, and a few boxes of Hornady for the days we want to see what the rifle can do.

A Short History of the 8mm Mauser

Germany adopted the cartridge in 1888 with the Gewehr 88, using a 226-grain round-nosed bullet at a little over 2,000 fps. The Gewehr 98 followed in April 1898. The big change came with the S cartridge, designed in 1903 and in service by 1905: a 154-grain pointed bullet at about 2,880 fps, fired from a wider .323 bore. Sierra credits it with pushing the US to turn the .30-03 into the .30-06.

A heavier 198-grain full metal jacket boat-tail bullet arrived late in World War I for machine guns and became the standard rifle load in 1933. That’s the round the Karabiner 98k, adopted in 1935, carried through World War II. After 1945 it faded from front-line service as armies moved to NATO and Soviet calibers, but Yugoslavia kept the M48 as its standard rifle until 1964, and Egypt, Turkey and Iran all used it.

That long service life is why so many rifles are still out there, next to the Mosin-Nagant and the Lee-Enfield on every surplus rack. If you plan to collect more than one, a curio and relic license is worth a look.

A Note on Reloading

Handloaders like this cartridge, because the mild American factory loads leave a lot on the table and components are easy to find. Bullets are .323 inches, in weights from about 125 to 220 grains, and new Boxer-primed brass comes from several makers. Sierra names a 150-grain spitzer for deer and a 175-grain spitzer for larger game.

We do not publish load data on this page. Use a current manual from a bullet or powder maker, and start with our beginner’s guide to reloading if you’re new to it.

Bottom Line: Which 8mm Mauser Ammo to Buy

• For a K98k, M48, vz. 24 or other sound military Mauser: PPU or Sellier & Bellot brass-cased FMJ for the range. It’s the cheapest new ammo and there’s nothing to scrub out afterward.
• For hunting: Norma Whitetail or Sellier & Bellot SPCE in 196 grains. Full power, and a lot cheaper than the American load.
• For a Gewehr 88, an old sporter or a rifle you’re unsure about: nothing until a gunsmith has slugged the bore and checked the chamber, and then only what the gunsmith approves.
• For a Hakim, FN-49 or G43: new commercial ammunition, with the gas system set for the load on a Hakim or FN-49. Leave Turkish surplus alone.
• For the best groups: Hornady Vintage Match.
