Do you know what a speedloader is?Yeah, anyone with a grizzly breathing down their neck...
Actually, I did pretty well at the local cowboy shoots using preloaded 1858 Remington cap-and-ball cylinders as *speedloaders* for my Remmy. Naturally, the Colt-clone single action shooters crabbed about how *unfair* my advantage was. These were the same dudes who complained that the holster I used, which is a family relic from the Wyoming Johnson County Wars, obtained by my Grandfather when he homesteaded in Wyoming, wasn't *authentic* enough.
Actually, for sustained fire, a single-action sixgun will usually outperform DAs and most semi-autos for sustained fire, say two or three boxes worth, unless the semiauto shooter has a hatful of preloaded magazines along- which some do. But just leave the loading gate on the SA open, fire a round, poke out the empty with the ejector rod, pop in a fresh round, and repeat until out of ammo. So long as you don't shoot at birds, you can keep it up at a pretty good pace.
