Starting an active retirement home for abused and neglected old double shotguns. in SASS Wire Posted June 19, 2018 · Edited June 20, 2018 by Pauldoe 22 hours ago, Warden Callaway said: Since I don't hunt with the old shotguns, I really load them light. I have used Grafs Reenactor black powder but more recently used BlackMZ. Since we can't publish load data specifics, I'll just say I load about 1oz shot and less by volume of powder. This turns out to be about half what would have been used in the day. Right - didn't know that we couldn't publish load data. Thanks a lot - I don't hunt so I plan to load light as well. Gracias!
