bumping shoulders on loaded rounds?

[got to go]

Thanks Dogleg, That explains everything. I think I would just pull the bullets and resize again.

Say you partially sized your cases (but not enough) or neck sized your cases one time too many and you have a pile of loaded ammo that chambers with difficulty or not at all. Or maybe you loaded ammo for one rifle and it won't chamber in another. You could size the loaded ammo a bit and avoid pulling them all down, resizing and loading again. It will work, but whether its a good idea is something that an individual will have to decide for himself. You'll never get Redding to recommend the practice, although I know there's a pile of guys doing it.
