You do realize he has no upper berm so there is nothing baffling the sound and you do realize I'm only 200 feet away down range right?? So you're telling me if I came about 200 feet from you and shot a 50 BMG and you had no ear protection on that wouldn't effect your hearing?
If the range is 100yds, that is 300', if you're 200' behind that, that's 500' from where he's shooting. If you want him to build the range the other direction, he'll be closer to you and it'll be louder for you when he shoots, presumably doing further damage to your ears.
A 50BMG @ 166yds isn't going to harm anyone's hearing.
