    I think your own experience and that of Sparkitoff pretty much tells you that there is a lot more to it than twist rate. There's a lot of "conventional wisdom" out there regarding ml guns and even when actual results contradict it.... well, somehow it lives on! :)

    Some other factors that should be considered are barrel condition (does it cut patches), Muzzle condition (again, is it cutting patches when you load it!), the quality of the patch material, and some others I'm too lazy to conjur up! All the factors that effect any round ball gun regardless of twist.

    For years original European Jaeger rifles were rifled one complete turn in the barrel length which could be very short ie 24 inches. These rifles shot round ball with great accuracy. Longcruise is quite correct in that there are a lot of factors that determine performance on target. Barrel condition, crown condition, depth of rifling and match of ball to patching and lubricant. Thinly patched round balls driven by a stout load of black powder may have accuracy issues in a shallow grooved barrel. Round ball wrapped in a thick patch can be very accurate in a fast twist 1 in 32 or 1 in 24.

    Enjoy your rifle.
