I have some deer fat:
This is one of the fattest deer I've ever seen. I have a pan full of trimmings from both internal fat and external. I'm debating using it. I still have a quart of redered fat from a couple deer taken 2 years back.
I plan on redering this and keeping them seperate. I did not do that last time, I just mixed it and cooked it out.
I shoot a lot of black powder and I think I'll be looking for some good formulas. I will start off using it in place of the oil in my present formula. I will have to reduce the bees wax as this stuff will be stiff.
