Substitutes

[Bunk]

I found out that APP will eat brass faster that Gunpowder. I was just lazy shot and did not clean the brass for a week or so. Brass goes into the scrap barrel and Bunk ain't happy.
My guns were cleaned the next day and other things took up my time.
Lesson learned so now I shoot and the next day knock out the primers, and soak in water with plain white vinegar about 1:4 with the water, wash, rinse and tumble dry.
Other than that APP by any name is a viable substitute for Gunpowder.
