Steve, those are some nice looking bullets. I was fooling with my toaster oven and some new powder tonight. Results with oven were good, powder not so much. But I'm on to why the powder may not work compared to a different type.Also I now realize that the powder that is working well is the weaker plain polyester, not the better stuff, need to make some changes.Subscriber, thanks for the info on the reaming, I'll have to read into it deeper.
You can get some interesting results by mixing a bad powder with a known good powder too. This is Cardinal Hammer white (great powder) mixed with a little Eastwood Mirror Black (bad powder).
