I'm useing a Redding type S FL die with the .288 bushing to resize my 6.5 Grendel cases. I'm measuring the shoulder position with a 9mm shell case and bumping the shoulder about .003. The body is being sized in the process. When I measure the shoulder position on the fired cases there seems to be a variation of around .003 but after the sizing the shoulders are consistent. Which means some are being bumped more than others. Are there any characteristics of the chamber preserved in the brass after this resizing? Should I be keeping this brass with the rifle it was formed in? I have another 264 LBC and a 264 LBC type 2. I started with Hornady ammo in all three rifles. Does it matter if segregate the brass with the individual rifles. My goal is to get to the most accurate loads that I can.

Does it matter if segregate the brass with the individual rifles. My goal is to get to the most accurate loads that I can. The various lengths are due to case extraction of the AR at work. Think nothing of it. No chamber memory occurs. I segregate by rifle but it's personal. Many don't. No harm in mixing but I want to track the brass a bit more. I load it and shoot it in specific batches and don't reload any of that batch until it's all shot. One other thing. The more under-gassed the rifle the less case variation you will see. Delayed opening cuts it down quite a bit. Greg
