[QUOTE="Kevin Thomas, post: 544484, member: 15748"] Hey Dennis, Sounds like you have a sizing issue there, which shouldn't be too hard to sort out. To begin with, nevermind what the RCBS directions said; that's just a starting point that [I]should[/I] work in most guns. To do it properly, the dies need to be set for [U]your[/U] particular chamber. That means bumping the shoulder back .001" to .002" or just a bit more. Start by lowering the die and trying the sizing process one stroke at a time. Try the newly sized case in your rifle until it chambers easily. Try another case, and see if it, too, sizes properly. Once they are all chambering easily, then lock the die and do the rest of the lot. Primers . . . there's another thread going on here right now that should give you some respect for the power in a single primer. That said, yes, you can size cases with the decap pin removed. Not enough in a primer to make a bomb out of the case and die, but they're still not to be taken lightly. If you need to decap these, this can be done, but it needs to be done very, very carefully.
