I actually put out a request on a few forums last year and came into about 1500 or so of them.. There are ways to make them target hulls.. Back in the day, I'd use a 1 oz Winchester wad to load 1 1/8 oz of shot and a 7/8 oz wad to load 1 oz.
I had a favorite steel shot load utilizing the BPGS-BP12 wad system that threw 7/8 oz of 2's or 3's to about 1450 fps utilizing Herco powder. I think I bought once fired and some new hulls from a few people in hopes that I would have enough to shoot that steel shot load for at least a few years. I still have aboout 1000 mixed Activ wads that came with the hulls that I got last year.. White, green, red, and blue wads which have some load data on the bags.
