I hear ya Coffinmaker, it certainly comes with some risk. I am going to knock together a clamp/ pushing device, it will be reamed to the external dia of the quill, then be slit with a couple pinch screws to get it on there tight, then the "breech" end will be threaded so a pusher can go the inside the quill.... (which I assume to be thru bored), and push it straight out of the barrel assy. From there... just some custom piloted end mills, time on the lathen a reamer or two and tada... a hopefully slightly improved product that will reside in the back of my safe while I move on to the next project.
Uberti certainly missed the boat on the Schofield and it's top break line, if you're a world class manufacturer of reproduction firearms and want to chamber it in a longer chambering than oroginal... just stretch the frame that extra .2", but no, now knuckleheads like myself have to obsess over mostly non-issues so we can get more than 6 shots shooting obsolete powder in our obsolete ammo, from our obsolete boomers.
