I currently have two black powder reproduction pistols; an Uberti 2nd model Colt Dragoon and a Pietta 1858 Rem. .36 caliber, also called the sherriff's model. I am thinking about getting a Howell conversion cylinder to shoot modern day cartridges (in cowboy loads). Just curious as to which one will work better or shoot better with the Howell conversion cylinder. The conversion cylinder will enable the 1858 to shoot .38 Specials and the Dragoon to shoot .45 colt. Any thoughts/experiences with shooting a Howell conversion cylinder with either of these repro pistols? Thanks.
