[QUOTE="Mikecr, post: 1341622, member: 1521"] This is not true at all. Seating/pulling force means nothing directly about tension. Neck tension is a brass squeezing force, and not a frictional force, nor a quantity of interference fit. A bullet under tension is released when pressure expands necks to release it. This is a relatively tiny force, and a super small distance. If the load actually had to overcome a 'pulling force' to release a bullet, it would likely blow up. Seating force is about friction, in itself having zero affect on pressure or MV. I know this through testing with WS2 coated/uncoated bullets under same tension, regardless of seating friction. If the wax you're using truly does not affect burn or fouling, than you can see that coated/uncoated, easy seating/hard seating, means nothing to pressure. On the flipside, actual tension means a lot. Folks, neck tension is not what you affect with lubes. You affect seating force, which affects seating depth consistency, and you affect ammo integrity. If the lube is moly, then you reduce pressure of the load as latent heat of vaporization comes into play. That's moly. You can also affect your fouling, like when moly or other lube vapors condense down the bore. These vapors do not just blow out, given that one side of the tube is sealed(chamber end). You can pull a bolt quickly on firing and see them in the bore. [/QUOTE]
