Good luck and Happy New Year!
I was demonstrating flintlock years ago for a shooting class the club did for high schoolers. Flint requires follow through

One target I shot at a ML match had a possible of 50, I only scored 49

There was a 2 or 3 second delay as the flint, steel and pan debated whether to fire it or not. They finally did fire it.

the 49 surprised me on that one. Any way, one of the members was photographing the class. He caught me with the pan igniting. I had always wondered, there it was, both eyes wide open
I sort of suspected they would be. At a Halloween night shoot I did not do do well. I had no night vision to see the sights.
I know what you mean about the rifle getting a bit heavy. My .33-47 is 16.5 pounds. I am beginning to wonder how I shot the 100 shot and a few other offhand matches with it in a single day with a 20x scope. Moving down to a 12x and giving up shooting the 36x on the .22.
A few nights ago I had a nightmare. My wobble are was inside the 25 ring, but the rifle would not fire. It would not be cocked. The trigger would not be set. Fired primer wasn't changed. Forgot the bullet. Forgot the power. It went on and on. The rifle never fired! I hope it was a night mare and not a premonition.
