Hi,
The 124gr. NATO 9mm should be at 1,260 fps, which is +P. Either something is wrong here, or Winchester is taking everyone for a wild ride.
Most of these loads are, per your test, performing WELL UNDER advertised velocities.
Also, in many instances, the uniformity isn't all that hot either.
The original DWM specs. were, 123gr bullet at 1,076 fps. Your Remington UMC 115 gr FMJ looks pretty close.
Query: Why would anyone want to shoot a bullet heavier than 124 grs out of a Luger?
