I bought some .450 Bushmaster, 7.62x39 (for .401 WSL too), .204 Ruger (also 240 Raptor), 10mm (for 9x25 Dillon too), some .32-20 (use in my .310 Martini as well), some .44-40 for forming .38-40 too. I think I got some .44 Mag. too, always use it, I make .401 GNR from it too.
The last deal was the .416/500 NE to make .500. But I found an odd one. This guy had 130+ pcs. of what he thought were once fired .500 3” NE Hornady brass. It looks like it spent months in a gravel parking lot driveway, dings all over the bodies. The brass is thick, it may iron and blow out fine. I haggled to about 1/3 his original price and no tax. Even figuring some losses, I should be able to FL resize, anneal, blow out enough to have a lifetime supply. It will be a bit of a journey. We shall see. Too hot to do much anyway.
