Shot this pistola at a match last month with smokeless factory "cowboy" loads and had no trouble. Went at it yesterday with my warthog 44-40 BP loads, first shot worked, after that cylinder wouldn't rotate, had to shoot all day advancing the next 4 shots by hand. Unloading and loading, or empty it worked fine, would fire the first boomer fine, then nothin'.
Now the "ULTIMATE 1873" model has a coil mainspring conversion, very light hammer pull, and a coil handspring (al a Ruger) conversion on the hand. If I give the cylinder a little resistance, the hand slips past the ratchet. So I'm wondering, do I need a stiffer coil spring on the hand, or switch it to a stocker? Or could the big boom be causing the hammer to bounce back, slightly advancing the cylinder out of time?
