I use Bore Butter as a case sizing lube for bottle neck rifle cases. I was having a real bad time with 30-06 military cases fired in my Garand sticking in the sizer die. Tried the Bore Butter about a year ago and have not stuck a case since. I just put a little in my hand and roll the body of the case in my fingers for a very light coat.
