I thought I would be ok, in HP, we are trying to hit a 7" 10-ring at 200y offhand. If you don't follow through, you can easily make what would have been a 10 into an 8. Then today... First time with a flintlock, every time my instinct was "hangfire"! I'll get used to it, but I think my 25y group is not terrible, especially considering the sun was hitting the trees.Larry, I have read that the very best flintlock gun is slower than a percussion gun when measuring time elapsed from the start of the hammer fall and the ball exiting the barrel. With very good locks the difference may not be perceptible by the shooter but it is there.
I suggest to the OP that he should try dry firing with the wooden flint by settling the sights (offhand of course) on a small spot somewhere ahead and see if the sight picture is the same as it was when he "fired " Once he masters that, plug the flash hole, prime the lock, and try the same thing. If the flash and smoke from the pan does not disturb his aim, he is ready..
Just need to figure out how to raise the group up. Maybe the ball/patch fit is not tight enough? I'll put a chrono on it next time. I could push the ball in with the ball starter by tapping it with my palm, I didn't need a mallet. I used olive oil.
