pulling some cast loads that were under performers, I had a small batch of imr 4895 out and dumped it into a h4895 canister, the black and green are mixed together.....this will be worm food, I broke my rule of one powder at a time, actually I just grabbed the wrong canister to empty it into....I know these two powders are close, one being just a little.faster but "never mix powders" is a hard and fast rule.of mine, a whole one pounder ruined cause I didn't think...okay gents flame me for my sins.
