I only use the AB in my 6.5 Swede at about 2800 fps on antelope. I have never got a pass thru, but with antelope, you usual don't have big problem finding them after they go down.

Might be the combination nd the 300WSM ,but I'd think that 180 AB would have stay together a bit better.

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
