Not very scientific but this pattern was at 30 yards with about 1 1/8 oz of #3 bismuth, hornet nest over the powder a thin felt wad greased with olive oil, shot and regular over shot wad. I charged it with a pretty stout load of powder by accident and was pleasantly surprised with how little it kicked and how well it patterned. I shot roundballs with 60 grains of goex 2f and she shot exactly where I was aiming. Unfortunately with the short days and sub-zero weather I didn’t get to shoot as much as I would have liked. I have next week off and will probably chase Hungarian partridge and sharptail grouse as there are a bunch this year. Maybe a pheasant or ruffy if I’m lucky. I have to mention, this gun has the fastest ignition of any large lock I’ve ever owned by a large margin and I’ve owned a bunch. I guess I won’t need to get her jug choked, this pattern is good enough and I haven’t even done any real load development. In my experience un-buffered bismuth usually shoots worse patterns than lead or steel so this is a good start.
