Thread: 6.5x55 hornady 129 gr sst with viht 160

    6.5x55 hornady 129 gr sst with viht 160

    Guys

    i'm struggling to find max and min powder weights for the above combo. The Viht loading data does not seem to cover it. Nor does my lee loading data book.

    so does anyone have any load data on 6.5 x55 using viht. N160 with 129 gr sst?

    Thanks

    Hi Pitnie.
    My Hornady Manual 7 Edition gives the following with N160 and 129 SST.

    Starting load- 33.4 grains.
    Max load- 43.6 grains.

    C.O.A.L. 2.905" WLR Primer and Hornady Case.

    Way too light. Vit load data for 130gr and N160 is 43-47.3gr.
    as to COAL do a search on this site there has been a lot of chat previously about the 129sst but about 3.055 is about right. Mine likes 3.045!

    I'm still learning so bare with me. So heavier the load more powder required? So if 130 requires 43-47 gr 129 should require a little less.

    Not necessarily it is all about pressure. The difference between 129 and 130 is very small and will make little difference. Start always at the lowest load and work up slowly until you find the most accurate. The data quoted is from the vit site so is correct for N160.

    Hornady 8th edition gives exactly the same numbers and they do make the bullets. Regards JCS

    Still would go with the vit data. Check searches on this site for 129sst and vit N160 will show that hornady data is very light and will be below deer legal energy if chronoed.

    No, no, no. Heavier bullet requires less powder. Regards JCS

    I would be very surprised if a load developed with the Hornady data failed to reach 2450 fps minimum velocity for Scottish use. Regards JCS
