Who To Believe

I can't even trust my own lyin' eyes because I don't have any M882 nor do I have a scale that measures fine enough.

According to TM 43-0001-27 (29APR94);

Cartridge, 9mm, Ball, NATO, M882 is a 112gr FMJ projectile propelled at 1,263±5 fps. 15 feet from the muzzle.

Cartridges of the World, 11th Edition (2006);

Under 9mm Luger it says "Military Load, US" is 124gr FMJ at 1,299 fps.  And in the US Military Ammunition section under "Cartridge, Caliber 9mm, Ball, NATO, M882" it says 124gr copper alloy projectile at 1,251±25 fps. 16m from the muzzle.

STANAG 4090 allows for bullet weights from 108 to 128 grains and muzzle energies from 400 to 600 ft-lb. muzzle energy and calling out that chamber pressure not exceed 47,000 psi absolute.

I'd long been under the impression that NATO ammo was 124 grain until very recently.  Now I have no idea!

    Winchester's Q4318/RA9124N are the same stuff as .mil M882 ball ammo.

      An Army TM is wrong? Where's my shocked face?

      Q4318 is loaded a lot slower according to Midway's page. 1,150 instead of 1,251. Is this like XM193 and XM855 where they're lots that have failed at some step in mil acceptance?
