R.U.,
I was hoping the same thing when I started, that way I could shoot all C&B except the scattergun, I figured I would just swap cylinders in the revolving carbine. Anyhow it is probably better we can't, the one I have fired (Dad had one when I was about 10) sure seemed to blow a bunch of crap back in my face! It's a shame though, especially since my favorite western is "El Dorado!"
