From reading the replies it seems that interlock generates mainly positive feedback. On more than one occasion though, I've heard "they work well at 30-06 velocities".
My question is how do they work on elk sized game at .30 magnum velocities?
I shoot a .300 Weatherby and I'm currently using Hornady factory ammo that's loaded with the 180gr Interlock projectile at a reported 3140fps - but my brutally honest chronograph suggests that they're doing a fraction over 3000fps.
Is this too fast for the 180gr Interlock on elk sized game?

Cheers,

Russ.

You'll probably never NEED a gun. In fact I hope you never do. BUT IF you do, you will probably need it worse than anything you've ever needed before in your life...
