The Umarex Hammer .50 is Umarex’s answer to the big-bore power question, and it brought something rare to the class: a magazine. Where most big-bores are single-shot, the Hammer feeds two rounds and cycles fast, all while making the kind of energy that takes big game. It is loud, thirsty, and heavy-hitting. Here is the honest verdict.
How we tested: Every pick here was run through our testing methodology. Minimum round counts, accuracy and reliability protocols, the failures that disqualify a gun. If we haven't shot it, we don't recommend it.

Big-Bore Power With a Magazine
The Hammer’s signature feature is that it is not a single-shot. Its two-round magazine and fast straight-pull bolt give you a genuine follow-up shot, which almost no other big-bore offers, and Umarex’s Lightspeed valve system cycles quickly for the caliber. With heavy .50 slugs it makes around 700 foot-pounds of energy, putting it among the most powerful production airguns and firmly in big-game territory. It fills to a high 4,500 psi through dual regulated valves, and despite the power it stays reasonably light and handy. For a hunter who wants big-bore energy and the security of a second shot, that combination is genuinely useful.
How It Shoots
The Hammer delivers serious thump, and the magazine-fed follow-up is a real advantage in the field. As with every big-bore, the trade-offs are loud report (hearing protection is mandatory), notable recoil for an airgun, and a low shot count, so a carbon-fiber tank or compressor is essential. Accuracy is good once you find the .50 slug your barrel prefers, and .50 slugs are heavy and not cheap, so factor ammo into the cost. It is a specialized big-game tool rather than a plinker, but within that role it does something almost no rival can: hit hard, then hit again.

The Verdict
The Umarex Hammer .50 is one of the best big-bore airguns for a hunter who wants maximum energy plus the rare luxury of a magazine-fed follow-up shot. It is loud, thirsty, and specialized, like every big-bore, but its combination of roughly 700 FPE and a two-round magazine sets it apart from the single-shot competition. Compare it with the field in our best big-bore airguns guide, and read our AirForce Texan review for the single-shot power king.
Our Rating: 8.5 / 10 — roughly 700 FPE of big-bore power with a rare magazine-fed follow-up.
