That’s a lot of busting. I use only range pickup brass too, but after I use it, it becomes mine and after I bust it once, it never needs busting again. Not so with you?
After a range shoot, my brass gets mixed up with any pick-ups I come across. So for myself, BB’ing has just become part and parcel of my 45 acp brass processing. It goes fast, and I just do it as a matter of routine.
Works for me, at least!
