So I have a .308 10" barrel AR pistol. Has worked fairly reliably using factory Federal Blue Box 150's. The local builder (110 miles away) just changed over the flash hider, tightened the barrel nut and returned it to me. I wanted to get my Eotech sighted in so since I have a bunch of Olin factory 147gr ball I decided to use that. The photos below show what happened on essentially EVERY shot, some were even completely turned aound inside the port. I have a few Ar's but no gunsmithing skills whatsoever. Anybody care to venture a guess on what is going on? Sadly since I am running low on the Federal ammo I did not shoot any of that to see if it behaved the same way. Interestingly, the rounds that do eject literally fly forward at about the "1 o'clock" position. Please offer any thoughts or suggestions. I really hope to not take another road trip
