everyone seems to have a different view on what the most useful, and versatile rifle for big game might be
but I see some options far more often than others in the hands of a group of guys Ive hunted with for decades
the rather odd thing is they all work nearly flawlessly in well-practiced hands.
what weapon you choose is far less important than how effective you personally become with practice in its use.
and how well you understand that weapons limitations and the games anatomy
heres a few of the more common

calibers 308, 358, 30/06 and 450 marlin

caliber 30/06, 35 whelen, 270

weatherby fibermark, in 300 mag and 30/06

tikka in 30/06
