Okay, it's not Newton's force. Newton was a guy, and they named the unit of force after him.
No. A Newton of force is not "1 KG times 1 meter per second." It is 1 KG times 1 meter per second-SQUARED.
I'm sure the Newtons above you are referring to are Newtons x seconds, which is a unit of Momentum, not force. You cannot measure the "force" of a bullet.

M = Mass
Kgs = kilograms
s = seconds
V = velocity (m/s)
Momentum = Mass (in kgs) x Velocity (in m/s)
Thus, Momentum is measured in (kg x m)/s.
Force = Mass x Acceleration = kg x m/s^2
One Newton of force is 1 kg x 1m/s^2
Newton times the number of seconds (or Newton x s) = (kg x m/s^2) x s = (kg x m)/s
Thus, Momentum = (kg x m)/s = Newton x s
Thus, the metric units for momentum is Newton x seconds or more simply: (kg x m)/s.
No one ever has attempted, as far as I know, to measure the "force" of a bullet, which is a meaningless concept. At any given moment in time, it has diameter; sectional density; ballistic coefficient; velocity; mass; momentum; and energy (and any other formula that is a composition of some of the above). But it has no force because it is not accelerating after leaving the barrel.
