Up to the third shot, things go quite smoothly and rapidly - no swabbing the bore, no ramming a bullet down a freshly fired barrel. About the third shot, the screw mechanism begins to clog up. By the fourth shot, the screw breech no longer opens. You'll need to dribble a bit of water on the breech threads to free it up. This happens, no matter how much grease you put on the threads. Fergie has a sensitive touch hole - if you don't clean it after every shot, it will begin to either misfire or hang fire after the 2nd or 3rd shot, and I've noticed that this rifle has some very lengthy hang fires. Click, whoosh, oops, nothing, darn it... start to lower the rifle and BAM! Exercise extreme caution with misfires, it can still go off. So it loads quickly, but if you take full advantage of that fast load, normal black powder maintenance will stop you after a few shots. There is also the flintlock mechanism, and the tray in need of priming. Very easy to get this wrong, especially if you are in a hurry. You can dump 3F powder in the tray and get rid of the 2nd flask, but you usually get slow ignition. Dump in too much, and you get the normal flintlock slow fire: click, sssssssss, pow!...
