Nix the idea for Imperial sizing wax. It's a joke compared to simple spray lube. I've got them both and never touch the Imperial. Maybe someday I'll try it for chapped lips.

All I do with new brass is run it into the sizer enough to push the expander ball through the neck to insure the neck is perfectly round. Anything more is a waste of your time and energy. New brass is ready to go.

Yes, you can chamfer too much. Do NOT get crazy with all the reaming, trimming, grinding and other silliness on your brass or you'll just shorten its life and ruin it.

RR is exactly right on the chamfering, a couple of twists is all you ever need.

Shooting the brass in either rifle should be fine so long as you FL resize. Brass coming out of automatic is usually still expanding and sometimes is so swollen it won't go back into the gun that fired it unless you resize,much less any other. But if you full length size, you shouldn't have problem unless one rifle has very small chamber. The guns will let you know if it's OK...real quick.[:-]

I clean my reloading dies about once a year. Be carefull about cleaning and stripping all the lube out of them or you may end up with your dies rusted because there was nothing to protect the steel. I've seen this happen to guys in damp areas who must store their reloading stuff in garages and other semi-outdoor places or have swamp coolers around.

If you're getting grease dents when sizing, that's a sure sign you are either using too much lube or slopping it on there it doesn't belong. Your spray on lube should eliminate this problem.
