Jerry, I must say that any of my opinions are based only on my own personal experience with my flintlock guns.
I gave up on trying to sort the good from the half truth in reading about these guns. I was determined to learn how to make my rifle work , and be reliable, and so I resolved to use them exclusively for all my hunting. When my chickens, or turkeys or goats are threatened by predators, I grabbed my flintlock. I'm now at the point where I have absolute faith in my rifle or smoothbore, but it was a sometimes steep learning curve. Reliability is #1 for me.
