We use to put push shotgun shell thru cardboard boxes and shoot the primers with BB guns. There were lots of bangs. Let along all the BB guns wars. Couldn't shoot above the waist. Till some thing dumb happened.
There is so many, I could go on for a month.
I shot and shot and shot at shotgun shells and couldn't get them to fire both bb gun and 22. We knew bb gun fights were dangerous but we didn't care. I was the youngest among older cousins and had the least powerful bb gun so I had to be close . I snuck up on my older cousin in a bale pile and poked him in the leg with my bb gun and scared the crap out of him. he begged and threatened don't shoot this close. I should have , I turned around and was walking away and he shot me in the back and damn near dropped me.
I wasn't there but neighbor boy got shot in the eye with a bb gun by his brother and bb was lodged in the eyelid. Their dad was our goto neighborhood veterinarian so he cut it out with a razor blade and no damage done.
I was always making mini cannons that shot bbs. one didn't fire so I used the cutting torch to make it fire but it got so hot that it burned my fingers so I threw it up in the air and the dirty bugger went off in mid air, bb hit the cement floor and ricocheted right into my upper lip and I bled like a stuck hog. I made up a story that I hit my lip on a tree branch snowmobiling. A few years later I was in the dentist for a chipped tooth and dentist took an xray and saw the round white spot in x-ray. I had to fess up and tell him what it was , both him and my dad got a chuckle out of that.
Nother time I loaded up some table salt in something and thought it would be like a sandblaster shot at the painted door in my boycave and it shot right through the door so I put a hanger thing above it and hung an old coat over it. Mom and dad found it many years later when I was in HS and asked about it and we all had a good laugh.
