    Did you watch the video? He compares 10.5 barrel performance with 110 Blk against Mk 262, BLK 2,200 fps ME 1,185 and 5.56 2,400 FPS ME around 970 with a 30 cal bullet 33 grains heavier. If shooting at 600 I would rather be using 5.56 with a longer barrel, but 300 and in with a 10.5 and a good bullet 300 is a winner IMO.

    To the OP's original question... a 16" AR with no can makes no sense in 300.
    This. If you specifically want a 16" AR that can do more than 5.56 (for instance, let you hunt in states with caliber restrictions, and extend your maximum effective range), 6.5 G is a better candidate than .300 BO, IMHO. I looked at this recently and went with 6.5 G. They're *both* boutique calibers--gotta accept reality either way--but 6.5 gives you the most ballistically.
