When I was about that age I begged my dad to let me shoot his double-barrel 12 ga.
He let me, not as a punishment, I asked for it. Damn near knocked me down. That is prolly where I learned to respect the Gods of Recoil ;)
My old man told the story of how he took his dad’s old double barrel 10 gauge down to the river to hunt. I’m thinking he might have snuck off with it as he was probably too young to be down there by himself with a gun.
It was (is I guess, my brother has it) an old Damascus spun barrel with exterior hammers. Anyway, my dad told me he thought he would be smart to get a quick second shot off, so had both hammers pulled back.
Except when he pulled the trigger and the one went “boom” - the other hammer fell and went “boom” about the same time. Knocked him on his butt. I’m not sure, but I have the feeling he was about 10 or 12 at the time (about 1930?).
The 7mm Mauser kicked my butt..cannot remember the rifles too much..but those shotguns..single 12 gauge..16 Remington pump, 12 Browning semi automatic,.. oh forgot the 30-30..and the 30 odd 6. Made a mahogany gun rack 8th grade wood shop.
