I completed my GPR flint rifle kit a few weeks ago but just haven't had the opportunity to get to the range due to weather conditions. I was able to finally take the rifle out to the range yesterday to see how she performed. I will confess this was my first time in attempting to shoot a flintlock rifle in over 30 years. I have spent most of my time shooting either percussion or cartridge black powder rifles. I was really anxious to try out my new GPR flint kit rifle. I had a difficult and frustrating time getting the rifle to shoot. At first I couldn't get the rifle to spark enough to ignite the powder in the pan and when I finally did get it to spark and ignite there was a delay from the time the powder ignited in the pan to when it ignited in the breach so the rifle would fire. By then I had pulled off target. I spent at least two to three hours at the range trying to get the rifle to shoot. I never could get it to spark consistently, more often not than would, and I never could get the rifle to fire without a delay when I could get it to fire. I was all over a 10" target at 25 yards. I have said all of this to ask do I need to harden my frizzen more and do I need to enlarge the flash hole and if so how much? Will doing these two things improve the firing of my new GPR kit rifle. I also shot my recently done TOTW Kit Carson percussion rifle and ate up the middle of the target but the rifle goes off when the trigger is pulled. No delay. Any advise would be greatly appreciated. Please accept my apology as I am really a novice to flintlock rifles and I am certain these questions or similar ones have been asked before.
