I go to our shooting ranges about a hour and a half before they open for shooting to look for brass and shift lead out of the berm for range scrap. What really surprizes me is all the live round I find at our two ranges. So far this year I have found over 80- .22LR, 3- 9mm luger, 3- .40 S&W, 1- .45, 1- .17 hmr, 1- .38, 1- .223, 1- 7.62x39, and two other military rounds I'm not sure what they are but they are big rounds. I also found 2- 12 gauge and 1- 16 gauge shot gun shells.
None of these even had the primers hit. Beside being dangerous if they are hit on the range these people must have more money then me to leave a live round on the gound and not pick it up and use it. They probably drop the out on a jam or during load a clip. Now we shoot the ones we have guns for and all have shot. I give out the others. I would hate to be the poor guy that has to mow the range and I hope he's got a armor plated deck on the mower and a bullet proof vest.
I also find and lot of .22LR rounds that the primer has been hit but didnt go off. I found that when we put these in our bolt action rifle with the stike turn 180 degrees 98 % of these fire.
