Frequently asked questions

What makes the InterLock bullet design effective for big-game hunting?

The InterLock mechanically bonds the lead core to the copper jacket, preventing jacket-core separation during impact. This design promotes controlled expansion and deeper penetration—critical for larger game at extended ranges where energy delivery matters.

Is 338 WBY RPM appropriate for long-range target shooting?

Yes. The 338 WBY RPM delivers substantial velocity and energy retention at distance. The 225-grain weight balances trajectory and wind drift characteristics, making it viable for precision shooting and hunting applications beyond 300 yards.
