Those Pedersoli 20 ga muzzle loaders are smooth bore barrels. I passed one up several years ago for $400 in like new condition. Now a used one goes in the $800 and about $1500 for a new. I am not impressed with the "saw handle" looks of the breech loaders but I swear I saw an original on an auction somewhere that had that same profile!? I was at the Tulsa gun show a couple of years ago and a man was carrying around a SXS percussion pistol. I looked it over and checked the bore. They were pretty clean and about .70 cal. wood looked solid, back action lock wouldn't hold on half cock but that was no problem to me. Probably Belgium. He said make an offer because it selling today to someone! I handed it back to him and walked away!!!! DUMB!!!!
