RE: Brass getting stuck in sizing die, whats up
Another really good lube is Imperial Sizing Die Wax. Just a tiny amount smeared on each case is enough and it works great. A little goes a long way. It takes a little more time than spray-on lubes, but it's not as messy and I've never had any problem with denting shoulders. I use it to neck down 7mm Rem Mag brass to 257 Wby. I did 50 cases and only lost one to a creased neck, and this was one step resizing straight into a 257 Wby FL die.
