Perhaps at the maximum distance little damage would be done, but I'd still hate to be hit by one at only a mile, for example. I wonder what the terminal velocity of a .22 caliber bullet would be if dropped vertically.
Not that it matters but I have seen my father and his friend when I was younger down a 600 lb cow with one shot to the head at about 25 yards or so.
Not sure it would work through a door but I respect the 22LR, also made a wonderful gun when jacklighting a deer at night when you wanted to be discreet.
For the record in the early 70’s times were tough for my family and others around us and nothing was ever wasted.
