I used to be a welder and for a year or so I worked inside pressure vessels where most folks did not want to work. There were always five to ten welders using air-powered chipping hammers--as well as my own chipping hammer. Talk about being inside the bell tower. That was also the time my girlfriend broke up with me and broke my heart. I had a new S&W mod 29 .44 mag w/61/2 inch bbl. I would take my heartbroken self and load up anywhere from 1,000 to 1,500 rounds of full-house loads a week for about 18 months and shoot carp in the rice field ditches where I lived. Now, I have constant ringing in my ears, can barely hear bells of any type including the bells on electronic devices, including microwaves and fire alarms. Just got my first pair of Walker Razor Slim Profile Electronic Muffs. I will be trying them out with my new .340 Weatherby Mag with an Acubrake. I will let you know what I think. In the meantime, don't let the young ones shoot without ear protection, And--skipglo, put a muzzle brake on your loudmouth. I can hear you from here.
