Does anyone make a drop in replacement barrel for a browning X- bolt short action? I’d like to just swap it out myself and not send it out to a gunsmith. Wanted to get a 10 twist for my 308. My thinking is I could run heavier bullets (180’s) for elk and deer then I could sell my 300WM which is pretty expensive for me to shoot at this time. I don’t think I’d take a shot past 600. Right now my 308 is a 12 twist and likes 150’s I tried 165’s and my groups opened up quiet a bit best I could get it was maybe 1.5 moa.
