RE: Big game calibers
I second B.B.A. on the 9.3 x 62...
Handles bullets from 232 to 320 grains, is capable of 250-300 yard shots and kicks noticeably less than a .338...
I have one in a CZ 550 American and it groups under an inch at 100 yards with Barnes 250 grain X bullets... Nice cartridge...
I've used mine on coyotes, whitetails, caribou and moose and it performed well... Everything I hit with it was DRT..
