    At GP2 (Springfield) yesterday there was a LabRadar set up next to the official BFTA chrono so we could all compare the results. The LabRadar uses radar to track the pellet and give a reading. (clever stuff!)

    The subject of inaccurate chrono's is a recurring theme so it would be interesting to see how well the BFTA official chrono compared with the LabRadar.

    When I went through, the BFTA chrono said 755 and the LabRadar read 753 - so 2 fps difference.

    If you shot GP2 at Springfield and you noticed what your velocity was on both chrono's - how accurate was the BFTA chrono compared to the LabRadar?

    803 on Lab
    815 on Bfta Chrono

    Noticeable muzzle blast/vapour on my shot.

    Set up on a Skan in similar temperature day before at 800-805... not that that's anything to go by, our CED M2 IR runs about 10 fps slower than the BFTA ones. Not sure how our Skan compares to our CED

    I have the Lab here so will find out which is closer.

    Same for me, but both were about 8 fps lower than I believe is correct.

    Lab was 6 lower than BFTA. 780 Vs 786. My Chombro was also 786 on the day.

    Big difference for me according to what's written on my card. (Edit: In typing this I realise I'm assuming the number underneath the BFTA chrono reading is the LabRadar reading)

    BFTA: 779
    LabRadar: 799
    (LGU, JSB Express 7.9)

    That's a pretty big outlier and I can't recall seeing the LabRadar display my value so I'm wondering about a transcription error (ie was it actually 779?)

    :oops: Ok so maybe two plus two doesn't equal five then!
    Well that explains it I guess, but the person who wrote it either doesn't do decimal points, or thinks JSB Express are 799 grains. :)
    In any case if you were doing it to 2 decimal places they're nominally 7.87 gr

    Might be interesting to know which guns/muzzle brakes were used.
    I used an EV2 MkII, standard muzzle.
    Tried before going on the course - 1fps difference.
    The chronos were after my last lane - still 1 fps difference.

    Steyr has a muzzle break of unknown origin, which has been fettled by original owner.
    It is an engineered tight fit that can only be removed by heating it - with a hair dryer!

    Pellet quality.gun maintenance. Chrono variation and the fact that you cannot hold the muzzle in exactly the same place means a wide variation of power readings between the two pieces of measuring equipment. The achievement is ? To get everyone s pants in a twizzle. Just MY opinion

    If you have the sort of pants that twizzle easily you'll always find a reason.
