With a round nose Interlock bullet, what is the minimum impact velocity that you want to ensure adequate effectiveness on a quartering lung shot on a deer?

Do you expect/see expansion at this lower velocity limit?

Do you expect/see full penetration (exit wound & blood trail) at this lower velocity limit?

I've heard some folks claim that round nose bullets expand at lower velocities but Hornoday insists (I've asked them twice) that the minimum impact velocity of all Interlocks, including the round nose bullets, is 1800 FPS.

And to this, I've heard some folks claim that expansion, while helpful, isn't needed for effective killing performance.


I hunt with a 32 WSP and never see deer beyond 50 yds, much less at 100 or beyond.

Still... one wonders...

Would love to hear first hand experiences
