[QUOTE="X-man, post: 812104, member: 8416"] I don't think case neck spring back has much to do with case hardness. The reason I think this is back in the day some benchresters used to turn their brass (tight neck chamber) so they didn't have to re-size the neck until they needed to move the shoulder back. I know for a fact the case neck is a lot harder after 5 plus firings yet the neck spring back was the same. What tends to complicate the issue is the neck thicken over several firings and this will start creating different spring back until the necks are turned back to spec. If I remember right the spec was 1-1.5 thou over all...very tight! Rifles set up this way shot well enough, but the slightest bit of carbon or whatever in the neck area caused significant fliers and pressure spikes. I never re size brass after pulling a bullet.
