Thank goodness for post #3, otherwise I'd be the only one.
When I started reloading I bought a pound of W-231, because it seemed like the best all-rounder for what I was planning to load.
Subsequently I ran into a guy at the gun show
who had bought out an estate sale, and had a bunch ow powder. He had one 8-lb, one 4-lb and two one-pound containers of Green Dot, I think a pound of Unique, a pound of Red Dot, a pound or two of 748, a pound of 760 and a couple others.
I went home, did some research, went back the next day and bought the lot (could not believe somebody else hadn't beaten me to the punch, but this was probably 8 years ago, when powder was easier to get.) Think I paid $125 for the whole mess.
Since then I've used up the two 1-lb and the 4-lb of the Green Dot, mostly on 200 gr .45acp SWC loads, but more recently on 125 gr 9mm cast loads. Just about to tap into the 8-lb keg, and guess what? Two weeks ago at the gun show I picked up another 2-lb container of Green Dot for $25.
