Yes I have used lots of dif shotgun powder in handgun loads.. I almost never load full power as it takes the fun out of it. I have a chit ton of red dot and unique at home. Since I travel a lot for work I take some basic reloading stuff. Have it set up in my travel trailor. So the only powder I could find was trailboss. I worry it won't get enough vol in th 44. I think max load is 7.5 gr. any one do 8.5/9 gr loads?
