I have been using my homemade Emmerts Improved bullet lube for about 5 years.
My Emmerts recipe has been working fine:
50% beeswax, 40% Crisco shortening, 5% Olive oil, 5% Anhydrous Lanolin
That is until a few new Hornady non annealed cases got mix in with my working cases and loaded with O.E. 2fg BP, CCI 350 mag primer, topped with a cast 20:1 Lyman 452664.
I got lazy did not anneal these extra Hornady 45 Colt cases because the others in the box had been working so well for years I though they be ok.
I fired of a couple boxes of my BP hand loads in my Ruger New Vaqueros and firing and ejection worked normally. That is until I fired one of the non annealed cases.
I had to hammer those cases out of the chambers. The blow back fouling formed a black tar that glued the cases in chambers. I got 1 or 2 stuck cases by tar ever cylinder full.
When I got home I cleaned and annealed all the cases.
I don’t know which ingredient(s) in the lube recipe is turning into tar so fast under the heat and pressure of firing BP.
I would like to eliminate that ingredient just in case it might create tar in my rifle chamber during an extended shooting session.
