I took my GPR to the range for the first time. Did everything right. Except did not remember to hold when flash occurred. I missed my first shots: one high and one low when I 'flinched' twice. Third and fourth time no spark; fifth time spark/flash but no shot. Sixth time, after cleaning frizzen and adjusting flint, hit target at 3pm second ring in. From then on, no spark.
I am trying to find a good knapping youtube but all I find is someone in buckskins in front of a fire talking about hammer and knife. I'll keep looking for a video that shows taking the flint from the jaws and knapping.
Again thanks for all the info and links.
So back to the range, first.
IF flinching is causing problems, as a new flintlock shooter you should first be using a
supported rest on a bench. (imho)
Do Not begin flintlocking with an unsupported rifle. The flinch may become a problem that is hard to cure if you do. Focus on the front sight post. You will naturally have a tendency to move the shooting eye off the sights and toward the lock when you fire. Sometimes it's the very minor motion of the cock, and sometimes it's the flash, or even both. This is natural as the human eye reacts in three stages, motion, outline, color. So what you are doing at the beginning is to train yourself to disregard that motion.
After you've done the bench for a while, then you switch to different shooting positions with various amounts of body support for the rifle, with the final stage being standing-unsupported, aka "offhand".
As for knapping, the best way really is to
pressure flake the forward edge of the flint. Yes tapping the edge of the flint when it's in the lock, using the spine of a knife blade or a special tool will "work" but it can stress the lock internal parts, and you have a chance to cause the slightly dull edge of the flint to become useless, instead of sharper. Pressure flaking is more controlled and gives you a better chance at restoring a good edge (imho)
Here is a video showing pressure flaking of a stone arrow head. The beginning goes right into the flaking. The principle is the same with the edge of a gun flint.
