As a kid got a bolt action 22 from an uncle. Old man told me not to shoot it. Couldn't resist and shot it. Some hardware (extractor maybe) missing from the bolt and it resulted to a fare size piece of brass case to be imbedded in my bicep after pulling the trigger. Dug piece of brass out with tweezers and hemostats. Figured I needed a needed a tetanus shot. Couldn't tell old man. Stepped on nail sticking through a board to assure I got the shot. After getting tetanus shot, old man gave me my first set of safety glasses. Cross between Buddy Holly and Drew Cary. Told me to get my head out of my a$$. Don't know how, but he knew what happened. Lesson one on safety glasses complete.
Lesson two. Shooting an old Daisy pump BB gun. BB hit concrete block and came straigh back. Almost. Hit squarely between my eyes and resulted in blood dripping. No real damage, no point telling anyone. But I knew I should have been wearing glasses. Let's not discuss steel BB shot at concrete.
Years later, the old man long in the ground, the payoff occurred. Pulled the trigger on a brand new TC Contender in 35 Rem. Long story short, factory installed scope base was too thick, creating condition where only a thread or two of the screws holding the factory installed scope base to the barrel were engaged - until the recoil from the 200 grain factory loaded bullet disassembled everything. Flying scope broke my glasses frame and spider webbed my poly safety glass lense (right lense only). Lesson three complete. Got a nice cash settlement from TC. And a nice scar and stitches to go with old hockey injuries that were lined up (mumzzy called it a waiting list for scars on her baby's face).
For what it is worth, find potmarks on my safety glasses that I use for shooting. I am not a welder. Only use is shooting, mostly flintlocks. Not looking to debate the 'never had a problem crowd'. Your eyes, your choice.
