I have a savage 110LH in .30-06, I want to try to get it chambered in something a little less expensive. It is mainly for caribou hunting with head shots under 200 yards. I have only put about 100 rounds or so through the -06 and have taken a couple dozen or so ' bou with it, but it is too expensive to feed. I am assuming the barrel I found on Midway will fit. Once I get the other one off, is it as simple as tightening it down and checking headspace, then test firing? I also see a barrel in .338 but that would be rather harsh for a 6.5lbs rifle. Accuracy below 1moa in .223 possible with this?
