[QUOTE="Mikecr, post: 554347, member: 1521"] It's normal to reach a point where shoulder bumping is needed. You don't have to FL size cases for this, and can just bump as a seperate independent operation with a Redding 'body die'(unless it's an unusual wildcat). There are tools just for checking shoulder movement called headspace gages. These provide for a relative measure/datum on the shoulders, and you can use one to measure the difference between good chambering and bad chambering of brass. You set a body(bump) die & size until you achieve ~1-1.5thou under zero headspace. This should chamber well. You don't want to oversize this as excess headspace causes brass to stretch back against the boltface(increasing it's length and challenging the action integrity). [/QUOTE]
