I recently discovered how to chamber a cartridge in my old B78 WITHOUT the hammer retracting to the fully cocked position. An easy procedure - momentarily squeeze the trigger at the commencement of the distinctive second (and final) stage of closing the lever. Note, I’m not sure if it also applies to the 1885. Thereafter, when the need arises, simply thumb the trigger back to the fully cocked position. In hindsight, it certainly beats the normal potentially dangerous practice of firmly thumbing the hammer spur, squeezing the trigger and then slowly lowering the hammer to the ‘safe’ or closed position - exemplified on a recent goat hunt when I accidently fired off a round when I mis-timed the uncocking procedure. Namely, I pulled the trigger without having a firm grip of the hammer spur. Fortunately, as is my usual practice, the muzzle was pointing in a ‘safe’ direction at the time.
