[QUOTE="J E Custom, post: 473837, member: 2736"] My best "Guess" would be that the back of the tool touched before it started cutting if it was single pointed. or the pilot turned in the bore and galled the crown. Ether way, this crown needs to be replaced because if you notice the land has an uneven bevel on it and there is no clean edge anywhere on the crown. As far as something happening at the factory, Murphy works there and it is very unusual to find a factory rifle that has a good crown. The factory rifles normally use a crown cutter and they dont worry about the centering very much. The only factory crowns that I ever saw that were done right were from the custom shops. There are some good crowning tools, and when properly used they do a good job. But I still like single pointing my crowns for consistency crown to crown. Occasionally I do one that I don't like and have to take another cut. I had an old master smith tell me that the last thing that effects the bullet is the crown and after that mother nature and the bullet maker had control. J E CUSTOM [/QUOTE]
