I have shot sub 2 inch groups at 100 yards with a 1 in 48 twist "compromise" barrel using patched round balls, however, the wind has to calm and the light has to be steady. On a cloudy day, when you shoot in the cloud's shadow, your point of impact will be different than when shooting in direct sunlight, and even a gentle crosswind can drift a roundball several inches at 100 yards.
Keep this in mind before you blame the load or barrel when you are attempting to shoot a 2 inch group at 100 yards.
The benchrest shooters put up a row of wind flags downrange and watch them and wait until the wind conditions are ideal before shooting.
