Sounds like a funny story but I can tell you from experience!
I shoot high powered Air Guns. Up to .50 cal!
Shooting one day with a .30 at a plastic stake out at 45 yards?
I had a couple come back at me and take out a window!
That's 90 yards round trip. If it could break the window?
It could have took out an eye!
So be very careful of WHAT you shoot at! NEVER shoot at Golf Balls!
Those suckers will send a round back at you with almost no loss in velocity!
