I have an aftermarket barrel for a large shank savage that fits the receiver terribly. Has a ton of play in it when it’s just threaded on. I can bottom it out in the action and back it off a half turn and have 3/8” play at the end of a 20” barrel. First noticed when I headspaced and installed it in the stock.. it was way crooked in the barrel channel. Shank diameter is 1.121 at chamber and tapers down to 1.1095 towards the muzzle. Barrel nut also has a bunch of play. Shouldn’t it be 1.120” all the way?
