    Chrono'd some 10mm today
    With the recent purchase of a chronograph, I've got lots of loads to test out. Today I decided to run some 10mm through my Chrony F-1. The loads were all factory loads. I could have ran a few more 10mm loads from Hornady and CorBon, but stuck with DT for this one. Firearm is a Kimber Eclipse 10mm w/22 lb recoil spring and Wilson Combat Shock Buffs.

    Uncomfortably warm and high humidity, about 85 degrees. Elevation is about 900 feet above sea level.

    CCI Blazer 200gr TMJ
    1076 fps
    1076
    1090
    1090

    AVG= 1,083 fps / 521 ft-lbs.

    DoubleTap 200gr WFNGC (Beartooth)
    1188 fps
    1184
    1203
    1218

    AVG= 1,198 fps / 637 ft-lbs.

    DoubleTap 180gr Speer Gold Dot
    1263 fps
    1273
    1231
    1222

    AVG= 1,247 fps / 622 ft-lbs.

    DoubleTap 155gr Speer Gold Dot
    1402 fps
    1370
    1381
    1394

    AVG= 1,387 fps / 662 ft-lbs.

    Not too bad really. I've been seeing DT's numbers putting up less than advertised velocity, and I wanted to see for myself. I know there are other factors such as temperature and elevation, but there's not going much of noticeable difference. I'm sure a 6" barrel would have raised the velocities some, but probably not more than 50 fps on average.

    Feel free to compare with some DT .40 S&W and some handloads I loaded up.

    I appreciate you posting this. I've been looking at some DT ammo and was wondering how they perform vs. their posted numbers.

    You're numbers aren't too bad and they confirm what I suspected, that DT's posted numbers were a bit on the high side.

    Who knows, maybe the humidity, temp, etc, came into play. Regardless I'm still impressed with them enough to get some.

    Nothing quite like a nice 10mm!

    Thanks again,

    DFW, I heard DoubleTap company is located in the mountains (?), or at least that's where they did the tests... so I think the elevation had a lot to do with the FPS as they advertised. :uhoh:

    Concerning elevation, and even temperature, I've always read that the lower the altitude, the higher the velocity and the warmer it is, the higher the velocity. Maybe I've read wrong or something, does anyone know for sure?
