[QUOTE="Mikecr, post: 813686, member: 1521"] I was responding to your post #13 in which you described BR reloaders fitting necks so that they didn't have to resize them, and my 6.5WSSM which is set up like this. While it's true that this is not practical for everyone, the condition does provide an opportunity to learn. Afterall there are relatively few out there set up like this, and fewer discussing it in forums. Brass does not flow. It's rolled or left in position as produced/reformed/sized. New cases are tapered in thickness from mouths to webs. Unless you turn or ream to address it, you have a donut(whether a problem or not). After removing it, the only way it returns -ever, is to roll brass back there(through sizing). This is not 'flow', but a chosen action. We choose this path through use of cartridges holding bad case designs, running very high pressure loads, using oversized chambers, FL sizing, or oversizing. Again, for reference and contrast, my declarations here are w/resp to my fitted 6.5WSSM. It isn't just fitted in necks but everywhere. And these attributes are true: Neck tension doesn't change because I don't size them, so I don't have to anneal necks, I don't FL size the bodies because I stay below ~58Kpsi in load pressure(from QL & tested to derive this), and I don't have to trim because I don't FL size. My current tuned load (mid node) produces 3025fps with 139Laps. I can reach a higher node at ~3200fps, but the gun doesn't shoot as well there, and I would have to FL size. No thanks. This cartridge example isn't practical for everyone. I know that. But it is a reference for what and why we do what we do: CHOICES We have choices. [/QUOTE]
