Recently found this percussion 50 cal CVA Mountain at a Pawn Shop. Could not resist. I have never fired one and as still needing to purchase all the goodies that are required for loading and cleaning as it only came with the ramrod. According to the only Internet source I found, they are very rare (only 500 made and very accurate). It has the 1:66 twist octogon barrel. Can I shoot any other "bullets" other than round ball? Anyone had any experience with this gun? Anyone know of the year these were made? Nothing on the gun except the serial number, etc. The barrel is 32 inches and the total length is 48 inches. Makes me feel like Davy Crockett!
