Is the lube just for the resizing part? I am going to do the liquid Birchwood Casey cleaner and I am thinking the process is: Lube, Deprime/Resize, clean, trim, chamfer, prime, charge, seat bullet, and crimp.
Also is Crimping needed on all .308 rounds or just ones that have the groove for it? Better to crimp everything and bee on the safe side?
I don't know about the Birchwood stuff? I can't recommend using anything petroleum based. Petroleum lubes can and will foul powder and primers. Proper case lube is so inexpensive, I'd get something marketed specifically for case lube. As far as the brass is concerned, case lube will only be required during the resizing process. If you're loading for an autoloader, yes I'd crimp them all. If it's for a bolt, slide, or single shot it's optional. Some believe in it some don't. I use both. Most bullets without a cannelure recommend not crimping, if you do choose to crimp bullets without the cannelure I'd recommend use of a Lee Factory Crimp die as it's easy to apply a very light crimp after the fact.
