This afternoon I had the fortune to shoot a 50 BMG rifle. It an AR-50 by Armalite, single shot bolt action. Ang bigat! Mga 34 lbs. at ang lakas ng muzzle blast, pero hindi masyado ang recoil (aray) dahil sa muzzle brake. ;f I have attached a photo of the empty brass together with some familiar ammo. Left to right: 9mm, 40 S&W, 45 acp, 50 AE, 223, 30-06, & 50 BMG.
