So .50Beowulf at 50 yards. I put a Vortex Strikefire II red dot on it thinking the recoil would break it. Well it didn’t. The Vortex works great. First few rounds were low as you can see in the pic with the white stickers. Second group after giving it a few clicks up weren’t far off at all, so I just started walking it in. The round was blowing out the wood target stands lol. I tell ya what, 350gr JHP .50Beowulf surely reminds you it’s not a standard AR with every round fired.
