nralifer Report post Posted October 26, 2014 There are many things that could be wrong. Be sure your scope is tight in the rings. The action screws are torqued evenly. Floating the barrel might help. If you know someone with a run out gauge ask them to check the run out on the ammo you use to sight it in and hunt with. I have found that COAL can be very critical, so check the recommendation of the bullet manufacturer, and get a Hornady bullet comparator. Also clean the soot from the muzzle brake with solvent that does not dissolve copper and see if there is any hint of copper fouling there. If there is, then take it back to the gunsmith and have him fix the brake. Finally I would be sure the twist rate of the barrel is appropriate for the bullet you are using. You can check the JBM ballistics web site and use their stability calculator after measuring the length of your bullets and the twist rate of the barrel. If all fails then have someone bore scope your barrel as the problem could be a bad chambering job. I had this happen on a barrel I bought from Pac Nor and had them chamber it. There was galling at the throat. Had to have the barrel rechambered. Shoots well now but lost an inch on length. Pac Nor missed it. Will not deal with them again.
