From the mouth of President Biden:

…which, if my trusty old math brain still works (oy), would mean that the 5.56mm poodleshooter comes out of Biden’s AR-15 barrel at 22,750 feet per second, by comparing it to the similarly-sized .22-250 Remington bullet (4,550 FPS).
The actual muzzle velocity of the 5.56mm bullet is, as we all know, about 3,250 fps.
So President Brain-Dead was exaggerating by a factor of seven, or flat-out lying, or he was just in his customary state of senile dementia. All three combined, of course, cannot be ruled out.
