    I took some various 40 S&W ammo the range today and ran it over a my chrony, I measured 10 rounds of each from my Sig P229 at around 84F.

    The results were:

    Hand. 165 Berry FP, 1.13 OAL 5.7 gr. Univ:
    Average: 1006
    Lo: 987
    Hi: 1020

    Hand. 165 Berry FP, 1.13 OAL, 6.0 gr. Univ:
    Average: 1035 fps
    Lo: 1025 fps
    Hi: 1041 fps

    Remington 165 gr. Golden Saber:
    Advertised FPS: 1150

    Average: 1071 fps
    Lo: 1042 fps
    Hi: 1093 fps

    Hornady 180 gr. XTP
    Advertised: 950 fps

    Average: 948 fps
    Lo: 937 fps
    Hi: 957 fps

    Winchester Ranger 155 gr. JHP (RA40155HP, $14/50 at Cabelas or CDNN)
    Advertised: 1195

    Average: 1176 fps
    Lo: 1155
    Hi: 1203

    Winchester 180 gr. White Box Self Defense
    Advertised: 1010 fps

    Average: 925.9 fps
    Lo: 917.6
    Hi: 936.7

    Hornady was closest to claimed velocity in my Sig, I was disappointed in the GS, they fell pretty far short, and were considerably snappier than the rangers.

    Not that I've shot it, but, in looking at the 40, the 135 to 155 grain bullets seem to give a great combination of bullet weight, and velocity, giving the 357 mag a run for it's money. I think the sweet spot for the 40 is in that 135-155 range. When the bullet weight gets to 165 grains, velocity plummets, and, the bullet size takes up too much of the case capacity, resulting in not good velocity, and, the bullets don't expand well, either.

    The same bullets, for instance Speer 180 grain Gold Dots, at 980 fps, FBI load, may penetrate 17.9" of gello, but, they only expand .60-70". That same bullet, 200 or 300 fps faster, will penetrate 15.5", and expand to .95" or more.

    I carry 155 to 165 grain myself, they are at the top of both energy and momentum curve for the 40 S&W.

    Things that I may need to shoot wear Carhartt's and Dutch Harbor Gear.
    I think I'll just stick with the 180 gr Gold Dots.

    The P229 is a glorified snubby, which is another factor in these figures. A mere 3.9 inches of barrel, part of which is chamber, is not a lot. I was at first thrilled that my agency just authorized the P226, in addition to the currently approved P229, but then I saw the P226 just gives me an additional one-half inch of barrel. I guess I will stay with my P229; it is reliable and superbly accurate. Thanks for the velocity data! :)

    Check out the official Mormon Gello results from Double Tap:
    Draw your own conclusions...

    Do keep in mind these snubby results from a Glock 27:

    Seems that factory ammo, out of a 3.48" Glock barrel, isn't really great.

    Sure is NOT the 18" the FBI load claims.
