I own a Pedersoli Jager flintlock which I really like. I love the way it fits me, however I am a round ball shooter and the twist rate was killing me so I had it bored out and rifled to .58 caliber, much better now, except I have always had trouble getting it to spark. Some folks say they have had great success with this lock, a few others seem to have had the same problem I am having. I have considered trying to find a quality lock that I could fit to the rifle, but this is really a long shot. I am using quality English flints from Track of the Wolf, and I have varied the length and position, up and down, of the flints, and nothing seems to help. The flints do seem to dull rather quickly. Any suggestions you can give me would be greatly appreciated, nothing so frustrating as a flintlock that will not fire consistently.
