I have an idea I would like to toss out for opinions. I was thinking of a carbine for my wife as she finds the long barrel on most muzzleloaders too heavy. Quite often the Hawkins are found pretty cheap at the gun shows. How about cutting the barrel back to about 20". Most of the Hawkins have a 1-48 twist. This is usually too fast for round ball and too slow for conical for achieving accuracy. Since pistols run from a 1-20 to 1-30, the 1-48 on a 20" barrel shoud be about right for round ball? End result, a muzzle light carbine with a good twist (read accurate) for round ball? I happened to pick hawkin because it has short fore stock and they are common. There are probably a lot of possible canidates.
