I have constant ringing as well. 29 Palms is the ammo dump of the US Military. It sounds counterintuitive to tell this to a board of hunters, but we were on more than a few occasions after a CAX, completely exhausted firing off rounds of ammunition. Just like everything else in the Marines, we did it until it was no longer fun, and then we did it 8-12 more hours after that. I dont know why exactly these rounds had to be cooked off, but theyd send us out with a 5 ton full of 50 cal, 556, mk19, m203 rounds and we couldnt come back until they were gone. The ammo just kept coming.
I also shot a Hoyt the first 5-6 years of their carbon bows. So its 1 of those 2 things that destroyed my hearing.
