Well I knew several men, long before I got interested in flintlocks, who had grown up with .40 caliber, caplock rifles. They had all been WW1 babies, their mommas getting pregnant as their dads enlisted and left for war, they being born in 1918... all three were living and hunting in different parts of Appalachia as teens during the great depression.
The .40 for them was the perfect rifle. It was the cheapest to shoot round ball with, and still have enough umph at 50 yards on a deer, and accurate enough to take the head on a rabbit or a squirrel or a groundhog, or a racoon, or a turkey. They were also very accurate at target shooting events, and in those days there was heavy competition for a small ham, or a side of bacon or some linked sausages.
So..., when I had a chance, I picked up a rather plain Jane version of one in flint.
