I have owned an S&W Sport 1 AR for almost 3 years now. I have shot about 90% steel case ammo through it since new. I now own a Ruger AR-556 AR. For the 3 months I have owned it I have shot about 98% steel ammo through it. I am currently disabled after working for almost 33 years. I live month to month on SSDI. Money is hard to come by thus, shooting steel ammo. I have done a few side jobs lately on my PC and can afford some cheap in price brass AR ammo. I usually buy 500 rounds at a time from sgammo.com Can anyone offer any suggestions as to where I can buy some cheap in price brass ammo? I would like to buy a minimum of a 150 rounds.
