LOL. O’Donnell is math challenged. Even if he knew the correct speeds (he doesn’t) at 30 feet, the time difference would be less than 1/10,000 of a second. Idiot.
Do be honest even I can figure out this idiot didn't mean muzzle velocity but rate of fire. He was too dumb to state it correctly.
How he came to that conclusion escapes me because every TV show clearly demonstrates that full auto ARs users, who never hit anything, are always brought down by 9 mil hand gun users.
