I've read that most of the original Navy cartridge conversions done back in the 1860's were designed for. 38 Short Colt cartridges? Loading old style heeled bullets would help with accuracy in our oversized '.36 caliber' barrels, which are actually. Pocket model cylinders are almost 1/8th inch shorter than full-size cylinders, so, that might require stepping down to. Who makes conversion cylinders for these 5-shot pocket models? Sounds interesting, but, I've only seen 6-shot conversion cylinders for full-size Navy & Army revolvers, etc. Now on the SliXshots, the Remington #10's work great. Back when I was using the smaller Colt factory 'pocket sized' nipples, I found that CCI #10 caps, which are the smallest ones that I could find, worked best. They limit each customer to 400 caps total. Just as I was about to run out of caps, my LGS received a new supply of Remington #10's & #11's, plus some Winchester Magnum BP #11's.
SliXshot nipples fit into my Colt Pocket Police just barely, and so far, I haven't needed to use cap guards.
