After work he headed over to my place and we drove over to the local rifle range(like .5 miles from my house) to sight in his MK 12 build and so I could fireform some brass. It was hotter than hell there, just sitting at the bench shooting I was sweating like you wouldn't believe. I told him to try out my .223AI, and he turned in this group @ 100 yards. There are 5 shots here. I was like . That's .263" CTC. Then, he was getting some inconsistent results with the Prvi 75gr Match ammo, so we ran a few through my rifle, and this is what 3 shots did. Not really great.
