I have had this gun for about a year now.I got it from Old South.Put about 50 rounds thrue it I have been using 30gr of Pyrodex with a .454 balls. What a joy to shoot . At 10 yards with a 2 hand hold not on the bags,it shoots in side of 2 inches at exact POI. Mine has the old 1860 Army cylinder. I have been thinking about some using some Triple 7 FFFG in it. That sounds like fun. I have a CCW,so I take out,just for the heck of it. It never has misfired ,or had a cap jam,yet At the range, it gets a lot of looks. What a fun gun to shoot! Would make one heck of a bedside gun! Just a note, they make a 1851 Navy Model too. My next gun {Navy} in ,36 cal.
