Winchester 223 ammo hollow point.
I will not buy this ammo again from Winchester as it looks like they have left the cases add on the range and pick them up a couple of weeks later. The brass is terrible looking corroded and has not been run through a polish machine. At the very least they could have cleaned the casings up before they loaded them. Very poor workmanship quality control needs to be reviewed.
I would not recommend Winchester ammo to a friend. At this point I don't even know if they will fire, most likely they will but the quality of the ammo is below par in the area of the casings.
