So I was thinking of switching from a .30-06 to a .270 Winchester perhaps and totally stick with the .270 for most of my big game hunting. I'm considering having them both but I mostly shoot at close to mid range, I have no need to shoot 500m etc.. plus the would be less maybe insubstantial but still would be helpful. So yeah ever since reading about Jack O' Connor with his .270 Ive been wanting to get one for my big game hunting; Primarily moose, I won't be going for brown/grizzly though Im capable, mainly moose and black bear are my targets, mostly moose. So yeah if I shoot em in the heart/lungs they'll go down if I do my part..
