Ipurchased one of these years agoand have found it will not go off unless when loading you turn gun on side and hit with palm of hand pretty hard a couple of times and then slam the butt of gun to the ground three times. If you don't follow this procedure it wont go off. A local gunsmith told me they had a casting problem with the barrels and there is an obstruction that keeps powder from reaching the nipple.Now that I've joined the forum and found out that several of you fellows know what your talking about I thought I would ask ifanyone else have this type of problem. The little gun is deadly accurate with 90 grains of black powder and a maxi-ball butitsnerve racking wondering if it will go off so I never carry it, Thanks
