Pl;ease to keep in mind that my comments apply to my quarter of MAINE.
Bear? Moose? NEITHER of which, at reasonable distances, (<200 m), will stand up to a well placed shot of a full sized MBR...or just about ANY shot from a .577, regardless of letters...
Don't be silly...I'm not talking HOOF or PAW, here...
From 200-400, it helps to be VERY good and VERY rehearsed as well as VERY sighted in!
At 400+, you'd have to be damn hungry, as well.
There are guys out there, heck, even ON this BOARD, that can make "that shot" with a .223. Or a .22 Mag. But, are YOU willing to BET your LIFE that you are THAT guy?
