I've got a .223 Stevens that shoots very well. I hate to use it for something else, but I hardly ever shoot it. I have a full custom .308 that I use for long range f/tr but right down the road from me a place holds 300 yard f/tr matches monthly. I am thinking about getting a pre-fit mcgowan to put on the .223 action for the short range matches so I don't burn up my barrel and .50$ bullets. I want the barrel to be 28" but can't decide b/t a bull or varmint contour. The matches are 3 rounds at 15 shots in 17 minutes. Is the Stevens action strong enough for a 28" full bull and would a Varmint contour be heavy enough for that rate of fire?
