Right now I`ve got about 1K range pick up cases, compliments of a friend. Most now are sorted by weight, brand, tumbled and preped. Funny part is that I never leave any of my fired stuff on the ground..it goes home with me. And as someone stated, out of my Mod. 12, I expect and get, excellent accuracy from which-ever bunch I choose to load.
A little work, maybe, but you only have to do it once.
