[QUOTE="Rob L., post: 2719142, member: 120811"] I've read that most size their brass to -0.001 to -0.002 thousands, which is exactly what I used to do. Now, I set my brass to 0.000" to +0.001". After checking each shoulder with a Starrett tenth digital indicator, I then physically bolt close on each resized piece to check that the bolt still closes freely or just a smidgen of resistance...a tiny tiny bit if any. I read about this method a few years ago. This set up suspends the cartridge between the bolt face and chamber shoulder, allowing best alignment to bore, plus reduced case stretch to some minimal degree. The method made sense to me so I tried it. I am NOT suggesting for others to do this, but once I tried it, it shrunk my groups and they were consistently better, especially with rifles that did not group as well as I wanted. Rob- [/QUOTE]
