I own one of the 1858's from Cabela's, however I purchased mine 8-9 years ago, so I have no Idea if they are still made by the same manufacturer. I had no idea that you could use a drop in .45lc cylinder on them. I assume that you would have to fire Black powder loaded cases. Correct me if I am wrong. I loved it, unfortunately I did not clean it the last time I took it out shooting, and it rusted shut. I cannot remove the cylinder anymore, nor will it rotate. The dowel that it is on is firmly welded in place. When trying to knock the dowel (or what ever it is called) out, I managed to break off the end piece; the part you would normally pull on to remove the cylinder. Ah well, some lessons have to be learned the hard way. I guess it would look nice on the wall now. It was great before I destroyed it, just to let you know.
