Please explain.3f is not for large bore smoothbore nor is patched ball
There are large numbers of us here who have great success with 3f in large smoothbores, one in particular posts regular success with even finer powder in large bore smoothbores with great regularity.
While a patched ball may not be historically correct for most smoothbores during most of the time period (there is evidence of its use late in the period by men in western Canada), it works well enough that most folks don't even consider trying more traditional methods....
What would be your criteria for patched ball or 3f powder not being for large bore smoothbores? What is your criteria for success?
