Recently when I was at my range another shooter hit me in the back of my head with the muzzle of his rifle.
Needless to say I talked to him about it.
When I work at a Range Officer I often have to stop people from pointing their firearms at other people. Most all these people would quickly tell you to never point a firearm at another person at the range, but as soon as they have to case their firearm, or pack up, they start swinging it all over the place. For many people muzzle awareness only starts and stops when they are thinking about firing.
And many times these guns are loaded. One of the holes in the roof of the gun club is from when a Range Officer told a customer to unload his rifle. That customer reached over and pulled the trigger to show the RO that the gun was unloaded.
It is also not uncommon for someone to load or unload their firearms at the trunk of their car in the parking lot.
As always, keep your head on a swivel. Don’t expect the people around you to be doing what they are suppose to be doing.
