    Hi reload guru's

    I am looking for a starting load or load range using VV N133 powder
    behind a 62 Grain FMJBT bullet in a 1/8 twist 16" .223 Semi
    (and preferably making the IPSC minor PF for rifles as well ;-) )

    I could not find this in the VV/Lapua load data and searching the web did not give some clear data back either. Any input very much welcomed.

    It is interesting that the latest Vihtavuori PDF doesn't show N133 with a 62 Gr FMJ, but there is enough data there, along with enough N133 data in similar calibers, that I could interpolate a starting charge. That my be what you have to do. I have only tried N133 with a 55 Gr FMJ.

    Thanks for the interpolation. I will post the results of the chronotest here. (under the usual disclaimer that these are my results and one should verify their on loads and i do not take responsibility for using my tested loads).
    I do not have the accurate numbers at hand at this moment (left them at home) but I reached some very nice results.

    Again, thanks for your time walkalong. Its very much appreciated and has been helpful in getting me on the right track.

    These are the results for the 62 grain reload chrono.
    Rifle:
    AR15 16" barrel mid length gas system
    Load and bullet:
    VV N-133 22.5 Gn, CCI SRP, S&B Brass, privi 62Gn FMJBT, light crimp (LFCD)
    Chrono Result:
    2603fps (or IPSC PF 161 ) avg 10 shots.

    So I keep working up a bit to the most comfortable load as the PF is apparently no issue. :)
