[QUOTE="Mikecr, post: 820114, member: 1521"] I'm pretty sure the neck has completely released before there is any bullet movement, and that 'pull force' means nothing really. -Take 10 cases with same neck tension, and polish/alcohol wash neck IDs on 5. Load all the same, uncoated/cleaned bullets, & shoot across a chrono. You will see no difference. This, even though seating/pull forces are significantly different with the squeaky clean necks, and challenging our ability to seat bullets equally with uncleaned necks. -Now test 10 cases with 5 partial neck sized 1/4 length, and 5 partial sized 3/4 length. This is where you will see a difference across a chronograph. It is simple grip force that affects bullet release, and not friction. Yes, there is blow by, before the bullet even moves, AND before the necks have opened fully to seal. [/QUOTE]
