Re: Upcoming Bison Hunt What Bullet?
I believe it largely depends on shot placement. I have seen plenty of buff dropped with rifles as light as a .243 with a behind the ear shot, which is how both of the guys i know that raise buffalo prefer to do it, and have seen several shot for slaughter with a .22 mag in the "magic X" from eye to ear at point blank.
Personally, with your rifle i would think any of the three bullets would give excelent results for lung shots, and you likely couldn't tell the difference in results with a behind the ear shot. My choices would go Berger, Nosler, Barnes, but that reflects my personal ranking of the bullets as well. Good luck on your upcoming hunt!
