I can’t believe how fast the lock time is on my Kibler Fowler, fast and consistent. I am impressed at how well the lock is engineered, it is a piece of art, it seems all the sparks are directed straight into the pan and It’s pretty easy on flints as long as they are installed correctly. English flints last the longest in mine. My gun naturally points as well and hits where you aim it. I was shooting PRB today and was shooting into about a 6” group at 40 yards off hand with a wicked heat mirage because I brought the gun out into -10f air and the barrel was still warm from the house, still shot well. My shot patterns have been very promising too. I did find some thin denim to patch my .600 round balls that made loading pretty easy. Anyways, it is a great gun and I feel spoiled to have a kit that not only functions so well but is historically correct and easy to put together plus it’s affordable, such a deal!
