I hear that!! Somebody mentioned my name
First, Long Johns Wolf is spot on correct. The Belgian made Centaures are VERY fine guns. Somewhat hard to find this side of the pond.
Don't know why. Many of them were imported. I would guess, those that have them tend to hang on tight. I would.
I'm a little confused by the OP. Not sure if what is being described is a Uberti or a Pietta. Uberti is always a problem for Barrel to Arbor fit and often jam the cylinder. Pietta will do the same, but for a different reason. First, as mentioned, don't drive the edge in "all the way." In fact, you shouldn't be able to. Normally, with a Pietta, the Barrel to Arbor fit is correct but the breach end of the barrel still contacts the cylinder face and needs to be dressed a bit to clear properly, and be squared up. Also, before a Pietta is put into service, the Cylinder locking bolt needs to be fit to the cylinder notches. Pietta does NOT fit them at the factory. The bolt almost NEVER fits properly and will
cause throw-by and peening of the cylinder notches.
Since you obviously have access to the internet, I STRONGLY suggest you visit "The Open Range." It's no longer active but has been retained as a "read only" site. Therein, Larsen E Pettifogger has a multi page tutorial on making a Pietta run. READ IT!! It will save you
major headaches down the road.
I, and others (Pettifogger) describe current manufacture Open Top Percussion guns as well made KITS!! All the parts are there, they just barely work. The require fitting and fine tuning to be user friendly. Once properly set up, percussion guns can be, and are, every bit as
reliable as suppository shooters (cartridge guns). Lots of invaluable information is available on this site. Take ya about a week to go thru it all. Enjoy!!
