Hello, everyone, I have been making my own bullet lube since the early 1970's. As far as that stuff Dixie Gun Works calls mutton tallow goes..save your money. Several years ago, I obtained fat from around kidneys of lamb & 1-two year old sheep. Rendered it down & had some of the nicest pure white, firm..almost like soft wax, tallow one could want. Absolutly no smell. I came across some of this tallow down on back shelf in basement..18 years old..and still firm & NO smell. Now it's getting hard to find around here, so I ordered some from Dixie..what I got was a very soft-slushy, yellowish colored, rancid smelling crap! Looks like I'll have to hunt around a little harder for the "good stuff"!
