We didn't have electric ignition back in the 50's when that series was made. Sorry. If you watch that scene and watch the flash in relation to the report of the rifle, and smoke coming out the barrel, its the real deal. That is why I noticed.
The true history of Boone is amazing. All the pulp novels written during his life, and since, are so much silliness. He certainly didn't mind " Yarning " when he was out and about. He had to convince people to pull up stakes, cross the mountains, and settle in a land they had never seen. And, he was a celebrity in his own life, only to have it all fall down around his ears in his later years, when land specutlators stole his lands in Kentucky, as well as all the land he has sold to other settlers, claiming improperly surveyed boundaries. Boone left Kentucky forever, and moved to what is Now Missouri, where he was given a title the equivalent of " governor " by the Spanish authorities to control the settlement of Americans in the territory. He was also paid a huge tract of land, which he used to either pay people for there losses in Kentucky, or exchange and give to Kentucky residents who lost their lands there to the crooks.
He paid off all his debts by the time he died, survived both the Spanish ownership of Lousianna Territory, and the brief ownership of the French, before it was finally sold to the United States. His ownership of his Missouri Lands had to be recognized by the States according to the treaties signed transferring title.( My Great Grandfather came from Kentucky to present Day Columbia and was listed as a founder of the town.) Boone lived into his early 90s, with one of his sons and grand children near Defiance.
He held court as a magistrate under Judgment Tree, which finally died and fell about 60 years ago.I saw the remnants of it years ago when I visted the historic site. They also had a black and white picture of the tree, taken in the 20s or 30s, before it finally died.
There still is a great dispute as to where he is buried as Kentucky supposedly bought his remains and interred them back in Kentucky. Now, some think that what Kentucky actually got were the bones of a Black Slave, and that Boone, and his wife, Rebecca are still buried in Missouri. No one can say definitively, today, so Boone is a part of history, only. He was one heckuva hunter and shot. He actually killed very few Indians, and no known white men. He would rather negotiate with the Indians than to kill them. In that respect, he was a very modern man.
