Imperial and one shot depending on what I'm doing but I do have a couple bottles of Forster high pressure case lube coming as I've read it makes resizing once fired Lake City 7.62 machine gun brass less of an overall pain. I can't wait to give it a try.
Forster says they put cold forming fluid in their high pressure lube, so beware. Some cold forming fluids have mineral oil in them, and it wouldn't be good to use around primers if that is the case.
