Out of his Black Diamond tell him to try two pellets and a 250 grain Shockwave. Like you, I can only guess what the penetration of the modern projectiles will be since I have little hands on experience. I normally end up hunting with a simple roundball combination that has been killing my deer for more years then I can remember.

The old myth of magnum rifles need magnum loads is busted. Too many shooters (and good shooters I might add) on this forum alone have posted results and targets of what a simple 100 or 110 grain powder charge will do and at some amazing distances I might add.

Which projectile is best.. I like the copper stuff if I want to penetrate or the shockwave type bullets. Yet I hunt with a pure lead 375 grain Buffalo Bullet SSB out of my Black Diamond XR (which will kill an elk by the way) because of the accuracy.



The big lead Buffalo Bullets are a Spitzer point and they really have good energy to them.



These shockwaves I was testing out on a real windy day. But had got some Triple Se7en powder that day and was seeing how well it shot these Shockwaves. Any of them would make excellent hunting loads.
