[QUOTE="Bullet bumper, post: 680203, member: 17844"] Squared up is way more important than length. The stuff about carbon rings , well if you are going to get a carbon ring then it is going to form no matter what length the case is. It will just form in a different place give or take a few thou. Clean properly and you don't get carbon rings. It is also important to not over chamfer the case mouth . You don't want the mouth edge like a knife as it will start the brass fretting at the case mouth and that encourages nicks and splits if they are going to happen in most cases they will not . Think of the internal case mouth chamfer as the muzzle crowing on the first barrel in the gun. That's a bit extreme because most bullets from bottle neck cases using slow powders are started into the bore by a tube of unburnt powder but it does have some similarities . [/QUOTE]
