I love them, I bought my first back in 1977, a custom flintlock in .45 caliber...I killed a few dozen deer with it through the years and won a few muzzleloading shoots that I went to back in the 80s...
I made a .54 caliber flintlock based on an early Lancaster design in 1988, still use it, have killed a few dozen more deer with it as well...
Guess I like them...
