I've got so much Berdan primed brass thrown in the scrap bin (probably a couple of hundred pounds), it's ridiculous! But like Chris said, I have so much Boxer primed brass in pretty much everything that having to make the hydro-press or find Berdan primers more trouble than they are worth.
Still, it pains me to toss it as it is good brass and I really hate throwing away brass that isn't too damaged to use. I guess that's why I haven't hauled it to the scrapyard yet.
