I can get 5.56 and 223 ammo but it is so darn expensive right now, and I need some range time!
5.56 mm and .223 are the same.
I’ve had good results with Golden Bear 62 grain .223 in my AR.
Brass coated steel case, feeds fine and while not as clean as the good brass stuff, it is noticeably cleaner than the WPA.
No problems with WPA except for being dirty, Tula doesn’t feed well for me. 5 out of a box of 20 didn’t feed properly. Get you killed in a crisis.
