I have shot several of my friends muzzle loaders and have enjoyed the experience. So I wanted to build my own. I have a thing for firearms that you can change the barrels on (multiple calibers/rifled or shotgun etc). I like to build box cases that hold the firearm, extra barrels etc.
I have decided to build an H&A Underhammer from Petaconica River Long Riffle Supply. I have even saved up the money.

But I cant decide on which barrel to begin with. A .36 for a cheaper to shoot target small game rifle. A .45 with a fast twist for long range. A large bore barrel, its awful fun to shoot a large bullet down range. Or a shotgun barrel.
Mostly it is for target shooting. I do go upland bird or turkey hunts.
What are your thoughts and reasons.
