After planting some game plots went to the range and tried patched round balls in my Encore. Tried 60 and 70 grains of Pinnacle 2F and 3F powder and patched round balls using a grease cookie and without a grease cookie. Best 50 yard 3 shot group was around 6". So much for that endeavor.
Swabbed the bore and and loaded the gun with 100 grains of Pinnacle 3F and the 250 grain Shockwave. No swabbing between shots.
Distance: 75 yards.
