have did a limited info search using black powder in plastic hulls and wads. so far it looks like black powder burns at high temperature and causes hull and wad plastic to breakdown ect. have never reloaded with black powder and it looks like a fresh start in components and maybe even reloaders equipment may be in order. anyone out there ever run black powder thru a MEC, P-W, Spolar, or any other progressive shotshell reloader ?
Yes. You can do it quite easily. However, you won't find a powder bushing that is big enough, so plan on buying a couple and then grinding them out to much larger capacities.
Fiber wads are the way to go. I've mined a lot of plastic out out of my barrels from plastic wads. Plastic hulls are not a problem, but they do get a bit toasted at the case mouth. For that reason, I rarely reload them a second time. I pick up hulls from the high school teams, usually Federal Top Gun and reload those and then toss them.
THE ANSWER IS “NO, DON’T DO IT!”
Black Powder is very sensitive to ignition by static. Whilst some powder measures (such as the Lyman 55 Black Powder measure) are made without plastic parts so as to be safe to measure black powder most are not.
You do not want a bottle of black powder exploding that close to your head.
This is another myth from the internet. Hundreds of thousands of blackpowder loads will be made this year using powder measures with plastic hoppers. Back "in the day" the Lyman 55 powder measure was made with a plastic hopper and that continues to work just as well as all the new powder measures with their plastic hoppers. Additionally, blackpowder is shipped and sold in plastic bottles today. Static electricity, of this sort, simply does not have the amperage to get the job done. Lightning bolts are another matter, so do not load in a storm while outside.
