Getting back to the caps that can jam the revolvers....if you recall in the old movies, the pistol-wielding guy would fire then lift the gun over his head, cock it, and then fire again. Before I had ever fired percussion guns, I thought these movie actors looked absurd doing that. The fancy-schmancy prissy show-off with all the unnecessary theatrics of lifting the gun above his head/shoulders to cock the gun. What I later learned (from books, and in practice), is that "lift-and-cock" motion was an effective way to avoid the spent cap jamming the revolver. The caps would fall out the top of the gun (the top of the cylinder was now on the downside after the "lift"). Whereas when the gun is cocked without lifting, the cap can fall, by gravity, into the revolving mechanism and the hammer mechanism and jam it.
The Remington New Model Army was far less prone to this (by design, as I recall, though I can't recall the specific design improvements) than the Colt, so I don't bother doing the "lift-and-cock" with m y Remington. I can't recall jamming up my Remington with a cap, whereas I don't want to recall all the frustrating moments when a cap jammed my Colts (Army, Navy, Pocket). So now I look like the show-off movie guy (I still think it looks prissy), but I have way less cap jams.
