briang2ad, I have salvaged many a bad crowns with this "fix". If you have a disk sander with a miter gauge (or a friend does) that will "square" up the muzzle and take off as little as possible. Once the muzzle is squared up again, I recrown with a Dremel Tool and ball/bell grindstones by "eye". I have had a lot of experience doing this so can "eyeball" this phase of the recrown. If you are not comfortable enough with this, then set the barrel up on a floor length drill press table and "center" the chuck with the bore center line and use the ball/bell grindstones. This should put you back in the "bacon"!................Dick
