I had a stainless Remington 1858 New Army BP revolver and the conversion cylinder from Taylor's. Even with the SS frame I could only shoot CAS loads. It was fun and made for a neat day at the range. Kids loved shooting it because it's a "Cowboy" gun with very little recoil due to the weight and light ammo. I used Trailboss to load CAS ammo down to about 740-750fps, if I remember correctly. It was fun for a couple years then Itraded the whole set off at a GS for something more fun.
