[QUOTE="Short Round, post: 399882, member: 20795"] I was going to say in the plug's instructions Sinclair says 0.024" below chamber length. I would be confident that they're being conservative too. It's the nature of their business. That said I follow their advice. Talking theory here, I'm assuming the tighter fit of your brass to the chamber the closer you could go to the actual chamber length as your brass shoulder is nearer to the stop, aka the chamber's shoulder. If you're full length sizing with a lot of headspace my thoughts are that you have more play and movement to worry about. This is probably why the bench rest guns can be run at much closer than 0.024". Like I said, I'm talking theory and nothing I've tested or watched or anything. [/QUOTE]
