Does anyone here has or use this brand before? I bought 2 boxes of TTI subsonic .223 from a local gun show and realized their brass is stamped with Winchester .223 on the bottom. The brass is basically cover in a black coat with scratches to reveal the nickel core metal, the primer is brass color and the bullet is molly coated. I would like to know if whether or not i got the genuine stuff. Also, i would like to know if these would reliably recycle the action. Just wonder if you guys would have an answer before i bother with calling TTI. I emailed them but no response. Thanks
