Yes. I have used up about 32 pounds or so over the past 10 years. They work well and save you a few bucks. It takes a little more time to work up a load and some lots are surplus for a reason (e.g. too much flash). The 50 caliber surplus is very slow and limits the use to overbore magnums and such. I think it is closely related to charcoal
. I've decided that for the price difference I'll stick with Powder Valley. The shipping fees are the same.
