I was talking to a friend of mine the other day who shoots a lot of BP and he told me not to waste my money on bore butter and all the fancy cleaners. He said he has used crisco for patch lube for years and never had a problem. He also said that he uses winshield wiper fluid and murphys soap to clean with and runs a patch with crisco down the barrel before he puts it up. I got into taxidermy several years ago and quickly learned that a lot of products with fancy names could be bought at craft stores for half the money of what the supply houses were charging.
