My barrel measures 2.422 with my Hornady O.A.L gauge. I did it 12 times it is reel consistent at that length. It is a Criterion barrel just seemed long to me. I never did a 223 always 6.5 and 308. I measured some of my 3 gun AR'S there all shorter but this is a 22" for long range shooting. Anyone have any ideas all loading data is for shorter lengths.
