A major green company producing rifles, shotguns, sidearms, and just began producing AR's made some RUM brass that is a bad joke.
My rifle is on the way up from Colorado so bought two bags of 50 pieces from Sinclair. Opened a bag to pull out a case and was astonished to see the flash hole visibly off center. Using the fingers of my left hand to stabilize the case, I slowly spun it with my right. The flash hole described a circle with only an edge actually in the center of the primer pocket. Another 39 cases were as bad or worse. Ten cases out of the bag had centered flash holes. I am not going to bother to open the second bag.
I ordered two boxes of 50 pieces each of the Nosler brass from Midway. Still waiting on the Norma brass backordered at Sinclair. I am really looking forward to trying theirs.
Check that brass before you drop the green.
