    The single 50 round box of 124 grain NATO I used was supplied by Brother Evil. Thank you sir!

    It was German MEN and is very hot. In fact, I found it too hot to use for anything other than my testing. It *could* damage guns not rated for +P+ and I will not use it with the A bolt where I found the recoil impulse to be much too violent with the bolt smacking hard against the rear of the lower receiver. The possibility of accelerated wear and tear just arenít worth the price of admission for me, As you can see, itís much hotter than the Winchester +P Law Bob referenced, but Iíve also seen it listed as being slower than the specs Iíve posted. All I know is what I felt. Itís hot.

    Caliber: 9mm Luger (9x19mm, Para, Parabellum)
    Bullet Weight: 124 Grain
    Bullet Style: Full Metal Jacket (FMJ)
    Bullet Casing: Brass, Reloadable
    Bullet Primer: Boxer, Non-Corrosive
    Muzzle (Velocity): 1284 fps.
    Muzzle (Energy): 461 ft. lbs.
    Very clean
    New manufacture
    Manufactured in Germany

    What's missing from this thread is ROF data! Where are the timers? Aren't there any engineers 'round heah? To start with I would choose three variables, two levels: 115gr vs 124gr, two different ammo manufacturers, and two subguns, and run a 2^3 factorial experiment measuring ROF with a pact timer... Then we could begin to talk turkey relative to the OP's question. I know - "OK nuge, knock yourself out!" Heh-heh maybe I will.

    Who's we??

    Working on it... Ammo manufacturers will be Federal AE & SIG. Subguns will be Uzi & Sterling. Figure of merit = ROF (rounds per minute). I have two timers, but will probably go with just the PACT. All materials are ready. Experiment design is as below...

    Any Predictions?

    Please carry on with the energy, dwell time, pressure, burn rate and charge debate... OP, please pardon my indulgence with your thread. Meanwhile I will post the results whenever I obtain one of those round tuits.
