Selected Hi Power Velocity Data

The below-listed velocities are based on 10 shots fired 10 feet from the chronograph screens using the Mk III pistol and factory barrel.  All measurements are in feet per second.

Obviously, this is not a complete list of all available 9mm ammunition.  I couldn’t possibly obtain all possible 9mm loads even if I could afford it!  This list can be periodically updated as new loads are tested for actual muzzle velocity.

Just because a load is listed does not necessarily mean that it is one I would “endorse”. It may have been chronographed simply for informational purposes.

Definitions:

Muzzle Velocity:  This is pretty self-explanatory; it is the velocity of the bullet as it leaves the barrel. In this instance, it is actually the velocity ten feet from the muzzle to avoid errors caused by unburned powder particles causing false chronograph readings.  In truth, we are actually measuring the “average speed”, which is simply the numerical value of the

Average Velocity: The sum of 10 separate chronograph velocities for a given load and divided by 10.  If firing 5 shots, the sum would be divided by 5 and so forth.

Extreme Spread: Within any group of chronographed velocities for the same load, there will be differences probably for each separate shot!  There will be both a high and low velocity reading.  The difference between the highest and lowest is the extreme spread. Small extreme spreads are usually found with the more accurate loads for the pistol being used but not always.

Std. Deviation: Think of this as sort of an “average” of how “consistent” the velocity of each shot for a given load is. We want this to be a small number if possible.  Accurate ammunition usually has a small standard deviation.
