I bought a 500 round case of this ammo from sgammo a few years ago and I did some chrono testing on it last september and my average velocity for 10 rounds fired from my M&P 40 was 985.22 feet per second. The high was 1017 fps and the lowest velocity was 947. The ES was 70 fps and my chrono was placed 15 feet from the muzzle. My fullsize M&P 40 has a 4.25" barrel and I use the stock barrel on my pistol.
During that same session, I also chronied some remington umc 180 grain jhp ammo and the average velocity for 15 rounds of that load was 950.5 feet per second. The high was 974 while the low was 919 fps. Lastly, I also ran some of my reloaded 180 grain .40 ammo using 5.9 and 6.1 grains of unique powder over my chronograph, as well. The average velocity for my 5.9 grain unique load was 951.8 feet per second while my 6.1 grain load had an average velocity was 1009.8 feet per second. Again, the shots were made about 15 feet away from the first (rear) screen of the chronograph.
