Well I built a 300 win on a older long action Savage I had to get into long range shooting. But the place I was planning on shooting is now closed and my Closest range is only 100 yards. So I decided to Rebarrel to a long action 308. So what will I need? Barrel, bolt face, firing pin? I have the lug and barrel nut already which are from Sharp shooters supply. Also I know I will need the 308 go gauge. Im going to have to figure out how to make the 308 feed reliably out of my Acis 300 win magazine. Anyone done this yet?
