You could get permanent injury if you don't flex up before impact .
Were you hunting Arby's?
I went home for lunch and to let the dogs out. While in the backyard, I heard a rifle shot couple seconds, I hear incoming round strike the yard. Another shot, hear the round catch tree leaves and hit plastic play toys in the neighbors yard. I live a couple blocks in from the country, town about 3000 pop. A couple more shots and I hear one pass over and another strike metal. I get on the phone and call 911 and get my dogs and the neighbors in the garages. I hear more than a dozen shots by the time a deputy rolls up and he is standing out front as a shot rings out. Yelled at him to get close to the house. We did not hear that round. I sent him in the direction where I thought shots came from and he found 2 guys little over a mile away, said they had been target shooting with the target in front of a temporary pond in a farm field. 12 shots from a 243 and 1 308. Later I found 1 243 105 gr sp had struck the neighbors truck, 1 went through the other neighbors garage wall past over their kids play area and hit the garage door and bounced on to the entry steps. He came back before I found the first bullet and said "he told them to be careful". I called him when I found the bullet after my neighbor left for work in his truck, he came back and I showed him the 243, deputy asked if I was sure it was a 243 , I was. He collected it in a evidence bag and left. He went and told the guys charges would come if the failed to pay any damage claims, 600$ hole in neighbors pickup grill. Not sure of the siding bill.
You heard the gun shot, then the bullet zip by? Seems odd figuring a 243 is faster than the speed of sound. You would think you would hear the crack of the bullet, then the report of the gun, like when pulling pits in competition.
