all that is correct but a lot of it does not apply. Most muzzle loaders do not push the bullet 2000 fps a few heavy loaders and smokeless shooters that use a muzzleloader will push up to 2400 fps at these velocities a 1- 28 or a 1-24 depending on the length of bullet will do the job what amazes me is that people using 70 or 80 gr and shooting 1350 to 1450 fps get such good accuracy, one thing in there favor is that there is very little stress or barrel whip with the very light loads.
