all i use is remoil or breakfree clp.......use it for everything...even in the bore..put it on my patches...my brushes...and i whipe the gun down at the end with it also....i like remoil because its real thin....a thick oil can gunk up quick if you use too much..but ive never had a problem with either.....some hoppes powder solvent came with my gun cleaning kit.....to me oil did the same thing......so i wont buy more...
