A word of caution about re-purposing powder containers.
I buy Bullseye powder in 8 lb. Jugs. I pour out a lb. or so into a one pound jug and use out of that container. With extended use the seal in the lid will be cut and separate. This happens when the seal is mashed between the lid and jug. This seal was foam and not paper.
A sliver of the seal got into the powder. This sliver was large enough to block the powder measure on my Star reloader. The first time I thought it was the powder bridged and shut off the powder supply. I poured the powder through a powder funnel to see if I could see any lumps of powder. No lumps so I thought I was good to go. It happened a second time. This time I poured the powder through a fine sieve and found the part of the seal in the powder.
I had to pull several hundred bullets to correct the problem.
Also finding the problem caused some gray hair. I have loaded 30+ years on the Star without a problem. It was difficult to analyse when what you have been doing 30 years goes bad.
