As per post #2822, I still have some of the Lee key drive slugs. I even found another box of them digging for something else, they are the 1 oz. weight. Let me know here or via PM if you want some to try out, all or part of 125 pcs.
I also found 22 .270, I know they are once fired, as I don't have or load for .270. I may have more, I should arrange my brass, if I find more they will become available.
If you might want to try a particular lead boolit, like deciding to buy a particular mold, let me know, I may have it and may even have some already cast. If I would have to cast some,(which I would certainly do), I could powder coat them, or use carnuba red in my Lyman 450 sizer. Gas check rifle and pistol boolits too.
