Well I checked the federal regs and this is considered a "Contender" type firearm. It can be swapped from rifle to pistol to muzzleloader to shotgun provided you use the correct configuration (i.e.: butt stock or pistol grip). The finished barrel is 16 3/4" and because the total overall length of the firearm with a butt stock on exceeds 26" I can use it in either the rifle or the pistol configuration. But I plan to only use it in the pistol configuration. I have other muzzy rifles to use.
Today using nothing but hand tools I lopped 10" off the barrel then polished the face with various grits of sandpaper followed by 400 grit emery paper (oiled). For the crown I used a 5/16" cap nut and cut the head off a 5/16" bolt to be able to put it in my drill. for an abrasive to polish/cut the crown I used FEL-PRO Clover Compound which is a silicon-carbide grease mix.
When all done I blued the face. Total time took about 2 hours. The longest time was truing the face of the muzzle using a square and levels and a mill bastard file.
Semisane said it best when he said something along the lines "that hacksaw is an imaginary tool that cannot cut a straight line" Even using a piece of angle iron as a cutting guide I went off on a slight angle.
But the finish job came out pretty good if I must say so myself. I'm happy with it.
