I'm just going on load data and factory ammo here, but the .30 AR is a .300 Savage, at least as far as you can go with 150gr bullets...and the .300 BO and 7.62x39 are no .300 Savage, they are a 30-30. I love the 30-30 in the half dozen levers and a mini-sharps, but it is no 300 Savage/weak 308. Perhaps the .30 AR is the 10mm Auto of rifle rounds. Too bad Remington didn't back what should have been a winning horse. I know, as rifle loonies, we split hairs...but the BO and 7.62x39 compare to this round like comparing a 308 to a 300 WSM/WinMag. I might be exaggerating to make a point, but the two you site seem to be pretty mild in comparison.
