....Do yourself and the gun a favor and leave it just the way it is now. Those guns were basically short-yardage guns and that's what kind of hunting is best suited for them. Yeah, I can hear the keyboards being fired up right now by some who have killed deer at 150+ yds. with them. I own a 1949 '94 in 32WS..my backup gun for deer and black bear.
.... If you need a scope to kill a deer where you hunt, use your .308 or '06...
