[QUOTE="Coyote Shadow Tracker, post: 2483621, member: 116439"] I know a TOP "F" Class Shooter and has chambered many winning barrels. He had a discussion on an off-center Chamber effecting accuracy. His point of view was that the bullet is leaving the Case in the Chamber at such great speed and in fractions of a second that what effects the bullet's travel is the rifling in the barrel. He purposely chambered a barrel off center , shot a "F" Class Match, won it, and then gave the brass to the person he had a disagreement with. The Other person places the Brass on a flat/straight surface and said "I can't use this brass-they are all crooked". My friend made his point. Don't always think that by looking at a chamber with a bore scope that it is not a good barrel and won't shoot. Maybe before you automatically send a rifle back to the Manufacture from just looking at it with a bore scope. Take pictures, contact the manufacture, and actually shoot the rifle. If the accuracy is way off then you have information and evidence to get the Manufacture to replace the rifle. Now the pictures (Post #19) of the Muzzle/Crown with the rifling having chatter machine marks in the land/groves - I would go back to the rifle manufacture. Personally I want to chamber a barrel to perfection, but there is a lot to say on how the barrel was rifled. You can have a great chamber and a terrible rifling process = poor accuracy. [/QUOTE]
