OK Guys, I have a previously used Douglas barrel chambered in .376 Steyr. Previous owner had it made 24" with a step at the muzzle to fit a Ruger front sight barrel band. I don't want to use one, so I want to cut the barrel back and recrown it. I have a 13x40 Jet lathe with a Bison 6 jaw set true chuck and an H&K barrel alignment tool. How accurately should the center of the uncut barrel bore be located? (Had little trouble getting it to +-0.001" spin eccentricity but is being a PITA beyond that.) Thanks!

Mike, Even as anal as I am about that, I don't think you could tell it if it were within .0001. Just make sure your cut is 90deg. to the bore. Butch | |||

Thanks Guys! Got it down to the point that the needle on the dial indicator just shudders a little. Anything wrong with an 11 degree crown? Mike -------------- DRSS, Womper's Club, NRA Life Member/Charter Member NRA Golden Eagles ... Knifemaker, http://www.mstarling.com | |||

I haven't seen anybody prove that the shape of the crown makes a difference in the way they shoot. Just need some protection from dinging it. Butch | |||
