I'm no wanting to start any arguments. I know there is a lot of indepent thoughts on whether or not you can have "unburnt power" if you load too much in a muzzleloader barrel. The following words are from a premier black powder rifle barrel manufacturing company, Colerain. Just something to think on... "Now, the advantages of gain twist rifling. For the person that wants to shoot only round balls through their black powder rifle you will not be handicapped, if fact you can realize greater accuracy potential and power. As the ball travels through the bore the increased resistance from the increasing rifling twist will allow for a longer and more even pressure curve. If we think of it this way, black powder or black powder substitutes burn the entire length of the barrel. If fact you can load too much powder and literally blow unburnt powder out of the bore. This is why muzzleloaders have such long barrels, to allow the powder to be fully consumed in the barrel and not on the ground. Gain twist rifle barrels help take advantage of the long powder burn time."
