First of all, my new Kibler gun shoots lights out. At least at 25yds with 40gns of fffg. Thing shoots in the same hole if I can see good enough to do it! I have some concerns though that are just gnawing at me. This is my first experience with a flintlock so I am hoping that the fixes are simple. First of all, my flints don't seem long enough to work consistently. I bought the TOW 5/8 x 3/4 English flints on a recommendation. When I have it in the jaws on half cock, I can't seem to get it close enough to the frizzen and still have enough in the cock to tighten down on. Secondly, all of a sudden, my hammer won't stay cocked sometimes. I don't want to shoot it until I get this ironed out. After I cleaned it, I put it back in the gun and it does this now. It started it while I was shooting and I messed with the little set trigger screw and it seemed to work better after that. Any ideas on these problems will be a huge help!!
