Whoa Goatlips.............not beef tallow. I should have said the tallow from Dixie is mutton tallow aka sheep tallow.
I got turned on to that from stuff from the ol' Felix lube formula, which BTW is excellent probably for BPCR, but I found way to much effort for CAS.
Dixie sells the stuff in small plastic containers, and I have had some stored a couple of years and it doesn't get rancid. Adding Crisco to the mix helps make the mix soft, but since I live in a pretty toasty climate, I found that adding the paraffin like you buy at the grocery for canning stiffens the mix.
I have shot my style lube with Goex, Goex Cowboy, APP and my current powder Goex Pinnacle and the fouling stays real soft all the way in my 20" rifle and of course my RVs too. The big lube bullets help a lot too, since they carry so much lube compared to regular bullets.
