FED PRM 17HMR 17GR SPEER TNT 50/3000

Description

Federal Premium’s Varmint & Predator line in .17 HMR is built around one purpose: putting small, fast-moving targets on the ground at distance with minimal meat damage and maximum effect. The 17-grain Speer TNT hollow point is the reason this load earns its place in that role. The TNT’s thin copper jacket is engineered to initiate expansion at rimfire velocities, meaning the bullet doesn’t just punch through a varmint — it transfers energy rapidly on contact, collapsing the structure of the projectile and producing the explosive terminal effect that makes follow-up shots on prairie dogs or ground squirrels largely unnecessary.

That jacket thickness is a deliberate trade-off. A thicker jacket resists deformation better through the bore and in flight, which tends to favor long-range accuracy. A thinner one sacrifices some of that robustness in exchange for reliable expansion at the modest impact velocities that come with a rimfire cartridge. Federal balances this by pairing the TNT projectile with consistent priming and propellant, so shot-to-shot velocity variation stays tight — which matters when you’re calling shots at 100 yards and beyond on small targets where a few fps of variance translates to a visible point-of-impact shift.

The brass casing supports reliable feeding in both bolt-action and semi-automatic .17 HMR platforms, and the rimfire primer configuration is consistent with what the cartridge demands for ignition reliability in cold or humid field conditions. Each box contains 50 rounds, making it practical for a full day of varmint work without burning through a case at once. Federal loads this under their Premium umbrella, which reflects the component and quality-control standards applied rather than just a marketing tier.
