I'm going to rebarrel my Rem 700 22-250 to a 250 AI. I'm thinking of a McGowen barrel in a 1-9 twist. It only comes in a 4 groove. I'm looking at shooting 75 gr Amaxs. I'm looking at 600 yard plus rifle. My questions are from what I've seen McGowen barrels seem pretty good what are others impressions? Will the 4 groove barrel be good for what I am wanting?
Thanks
