While I agree with you ought six on many points there are a couple that I guess I might hold a different opinion.
1:48" twist is a compromise between bullets and balls. Truth is, 1:48" twist doesnt really work well for anything.
I have a number of 1:48 twists which are outstanding roundball shooting rifles. Not that I would enter them in a shooting competition, but for hunting they are more then acceptable. While I am not saying all 1:48 twist are, there are many moderate twist barrels what will hold their own with many of the "roundball" barrels. Their advantage is many of them will shoot conical loads well at the same time. Which makes them a nice all around twist for the average shooter.
Round ball guns are only good for 100 yards or less.
The reason many people consider roundball rifles a 100 yard rifle is the amount/degree of energy the ball has lost at that point. While there are cases where roundball have taken game all the way to 200 yards, the "average" roundball shooter does not have the skill to make such shots with their rifle much further. As you said, the limitation of the roundball is by ones ability to place the shot. As much as I practice with a number of roundball rifles, I would still limit my .50 calibers to 100 yards and the .54 and bigger to 125 yard tops. That's the best I personally feel comfortable with. If a person and their rifle can only hit and produce an average group at 50 yards, then that is all the rifle should be used at when hunting.
Also the FFF prime is good advise. I have two pounds of FFFF which I have slowly been shooting off now for a couple years, when I was told I
needed it for priming my pans...
