Depends on the revolver
You will have to define "good". Cowboy Action loads are low pressure lead bullet loads.
the initial colt revolvers were cap and ball loaded. 1873 colt converted to the brass cartridge loads. making them easier and faster to re-load.
Unlike a current day S&W or Colt, the cylinder does not swing out to load. By flipping the loading gate open, you can load cartridges into the cylinder one at a time. When closed, it keeps the cartridges from falling out.
I can load my charter arms bulldog pug 5 round .44 special revolver in 6 seconds without a speed loader.
Depends on the load
The Model 1 uses standard .45 Colt (not .45 Auto- .45 ACP) and 2.5 inch .410 shotshells. However- this is a fairly small handgun- and the .45 Colt is not a small cartridge. You will likely find recoil very unplesant with standrd .45 Colt ammo. Several companies do load a reduced power "cowboy shooting" version of the .45 Colt, which would reduce some of the kick.
