That's the kind of info I'm looking for, thanks. I posted before I looked thru my cast bullet manuals. I found a lot of data there on 4759 in a whole bunch of calibers. None of them are earth shaker loads but seem to be great for plinking ammo. I was thinking of the 7TC/U and 45-70 among others when I got the powder. At the levels I've seen ,the brass SHOULD last forever. I just hope I'll be able to get WW's for casting!
