I don't participate in this forum too much but that is absolutely beautiful! I've been thinking about a Lyman Great Plains rifle in flint and have had percussion rifles in the past. For those who have flintlocks (which seem to be in the minority), how do you like them? Do you find the lock time to be any disadvantage?
There is no choice for percussion in the post Christmas primative season in PA, flint only.
The speed of the ignition varies. Some are pretty fast.
Naturally the lock work is important. I saw a huge difference between a standard Thompson Center lock and a L&R RPL lock. Flash hole position relative to the pan is also a big deal. Generally the hole should be higher than the pan because the flame rises. I can see the difference of speed between my RMC with L&R lock and Thompson with L&R lock due to the Green Mountain barrel on the RMC. The RMC is quicker.
Most guys say, and I believe a half pan is quicker than a full pan. Pan powder gets slower as it sucks up moisture, so if it is foggy I dump that powder often. Once you fire, the burnt powder makes the pan/charge suck up water. You can clean that with an alcohol wipe or fletch dry-aluminum oxide.
Entry level flints are usually not at the same level as a good custom job. A good lock like a L&R or Siler lock is generally a good upgrade on a production rifle. Original/cheaper locks can be tuned, but a shortcut is a good drop in "speed" lock. Generally speed is everyone's goal.
