Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass and velocity), which to some degree reflects the recoil impulse from the firearm onto the shooter (see section on limitations).

Footage released showed the rifle intentionally aiming off target so the bullets could correct their flight path. EXACTO technology is claimed to markedly extend the day and night-time range of current sniper systems. [4] [5] How the ammunition is designed to change direction in mid-air is classified.
