I carried a rifle when I was 13 years old...without an adult along.
I never shot anyone....unles Brer Rabbit counts.
So far as owning a Vulcan, who do you think owned cannon in the colonial period? They called them “Privateers” for a reason.
Also, check out this list of the Mormons in their westward migration: The group consisted of 143 men, including three blacks and eight members of the Quorum of the Twelve Apostles, three women, and two children. The train contained 73 wagons, one cannon, 93 horses, 52 mules, 66 oxen, 19 cows, 17 dogs and some chickens, and carried enough supplies to fully provision the group for one year
Well I think a lot of us did that when we were kids.
But do you carry a .22 rifle to work with you or the grocery store? By the way if you do fine by me. :-)
