[QUOTE="Mikecr, post: 519124, member: 1521"] Lube shouldn't make any difference at all. Neck tension is not directly represented by the force it takes to seat bullets. There is friction as well. But this does not come into play with bullet release on firing. Neck expansion from pressure allows bullet release, before it even moves. Neck lubing allows easier seating, which should provide more consistent seating, if the plug is pushing too hard against the angled bullet nose. But when this is the case, you're not sizing necks correctly. Neck TENSION is purely a matter of it's springback, which is limited to ~1.5thou(per side) with very very hard brass. You'll note that others have solved the 'problem' of varying seating pressure with annealing. Well, annealing doesn't make necks slippery. It normalizes & reduces springback, and so tension variances. Phorwath, there is no need to use wax in the necks. There is no need to lube necks. Just size them correctly, with an occasional annealing, and all will be gripped consistently. [/QUOTE]
