[QUOTE="Mikecr, post: 2590232, member: 1521"] I doubt dry lubes and other frictional levels will make a difference to MV. Wet lubes could cause a hydraulic suspension, non-gripped condition, and should never be done IMO. Setting up for a few weeks could matter (regardless of dry lube). The thing is bullets are not normally pushed out of necks, but released from necks with neck expansion(which is always 1st expansion). Normally tension grip is lower than purely frictional grip. So the neck expands any amount, and the bullet is swinging in the wind from there. Given this, it doesn't matter what your seating friction is, as that doesn't change tension (a bullet gripping force). But with a wet lube your friction could actually drop to near zero, and then no amount of tension, high or low, would matter anymore. There would be nearly nothing holding the bullet from either leaving, or pushing further into, necks. So a bullet could then move before neck expansion. That could play hell with a load.. [/QUOTE]
