I bought these awhile ago. They are made for 1.66 twist barrels. I also wanted to know if they will shoot in faster twist barrels. Such as inline ones. I contacted Hornady about it. They said yes. So i ordered them. Figured if they don't work for my inline. They will be fine for my flintlock. Today i shot them in my CVA wolf. Right on the money. I had about a 2-3 inch group all close to the bullseye. Much cheaper than power-belts. And no patches needed. So now i can shoot my BP rifles for less cost per round.
50 of them for 18 bucks is not bad. And where i get my BP supplies always has shipping deals.
