[QUOTE="Mikecr, post: 354038, member: 1521"] BigGreen, it's true that none of my cartridges grow. Right now I shoot 223, 6br, 6xc, 6.5wssm. If your cartridges do, then of course you will have to trim to stay clear of chamber end. If you look at your fired brass for shiny mouths, you can see such a condition coming on.. All I'm saying is that precision in this isn't necessary. Sufficient is good enough. It will not cause accuracy issues or severe pressure problems, unless you let it get way outta hand. And Gene, Same with turning onto shoulders. There are no neck-shoulder junction concerns, or uses, beyond donuts and potential initial headspacing. With the correct cutter angle anyone could turn needed amount of the first 1/8" of shoulder. Thats One Hundred and Twenty Five Thousanths.. I don't cut anywhere near that far down. I don't need to. But wildcat forming might require it, and if so, there is nothing wrong with it. Nobody can tell you how much you need to go up on a shoulder. There is no spec or standard for it. You might not need to at all, or stop at a point before reaching the shoulder. Just depends on what your needs are. On the flip side, I'm not suggesting anyone with a wrong cutter dig it into their shoulders to cause separation. Such a lack of common sense cannot be acounted for in my perspectives. [/QUOTE]
