Federal Champion Training BYOB .17 Hmr ammunition (part no. 770BTL250) loads a 17-grain Speer TNT Jacketed Hollow Point for varmint hunters who want fast, explosive results. Federal has been a top American ammunition maker for decades, and this loading reflects the same attention to consistency found across its premium lines. The thin-jacketed hollow point is built to fragment violently on small game and pests, trading penetration for explosive terminal effect at rimfire velocity. Brass-cased and 250 to a box, it is built to feed reliably through any firearm that cycles standard factory ammunition in the chambering. In our rimfire ammunition lineup, this .17 Hmr loading is a confirmed, dependable choice worth adding to the cart.

Frequently Asked Questions

What is the 17-gr Speer TNT Jacketed Hollow Point suited for? It is built for varmint and predator work, where fast fragmentation on small, thin-skinned targets is the goal, not deep penetration on big game.

How is the Speer TNT Jacketed Hollow Point different from a standard cup-and-core bullet? The hollow point cavity is what starts the expansion process on impact; without it, the same bullet would behave much like a solid, non-expanding round.
