i have the same rifle, and plan to shoot tha ball with .15 patch and 70 grs of blackpowder, real black powder. was at the range last week and put 27 rounds in the paper. with 3" groups at 100 yds. most with two of three shots touching each other. just waiting for a deer to be the next target. good luck to all this season. here in pa the buck are running all over in pike county. with the 4 point rule from last year. lots of good bucks. got a eye on a real nice ten.[8D] bob
