Hollow-Point Boat Tail (HP-BT)

Hunting Match

Hollow-Point Boat Tail (HP-BT) bullets combine expansion capability with superior ballistic performance. The boat tail base reduces aerodynamic drag, maintaining velocity better at long range and resisting wind drift. This design is popular for match shooting where the hollow point improves balance and accuracy rather than terminal performance. In hunting applications, HP-BT bullets offer both precision at distance and effective expansion on game. Sierra MatchKing is the most famous HP-BT, though many match bullets use this configuration.

FAQ

Are HP-BT bullets good for hunting?

Some are, some aren't. Match HP-BT bullets like Sierra MatchKing have small cavities that may not expand reliably on game. Hunting HP-BT bullets (like Hornady ELD-X) are designed for terminal expansion. Check manufacturer recommendations.

Why do match bullets use hollow points?

The hollow point in match bullets improves accuracy by moving the center of gravity rearward and providing a consistent meplat (tip). It's not designed for expansion—many match HP cavities are too small to expand reliably.
