[QUOTE="Mikecr, post: 519146, member: 1521"] The neck expands enough to release a bullet(.0001) before the bullet actually begins to move. The escaping gas(around the bullet, and before neck sealing) scours the throat and soots the outside of necks. So it doesn't matter to peak pressure, throat life, or neck sooting, that you coat bullets or not. Actual neck tension matters to peak pressure, and neck sooting(depending on clearances). You can run an independent test over a chrono to see it. [/QUOTE]
