RE: I fit both criteria!
In my .62 caliber I use 80 gr Pyrodex RS and 100 gr of #5 shot in a Winchester AA wad. It will roll a coffee can around out to 30 yards and that is good enough for me. I tried to pattern it one day and discovered it shoots 2 inches to the right. I have not changed the sights yet, but that does explain why I missed a couple grouse this winter.
