To Mikecr's point, it's not going to do you any favors with respect to concentricity and consistent seating depth.
Perhaps some Redding dry neck lube on the case necks will help with the expander button?
i did try neck lube too to no avail..... both dry and the sizing wax (at different times of course)
as to RTK's question... i'm not sure it really does in this gun... the best groups i've every shot at 1000 yrds was with this gun. only problem is i wasnt measuring runout at that time and have no idea if the ammo at that time was consistently concentric or not....
my groups have been pretty good recently since i started checking bullet and neck run out for this ammo but i have had the odd flier and i would love to blame it on runout and not just the shooter
maybe i should never have measured it, ignorance is bliss...
but when i'm shooting against my buddies at 1000 yrds for who buys breakfast i want to make sure i can rule out all of the variables....
