  • Hi i have had a few emails on the conversions from ADI data to the Hodgdon Extreem you all know the Hodgdon powder is made here in Australia and just repackaged for the us market here is ADI's website and the conversion.


    Bench Mark1
    Bench Mark2=BenchMark
    You will notice other ADI powders that DO NOT have a CONVERSION THEY ARE DIFFERENT they are faster than there similar name if you cant find data for the SLOWER HODGDON Equivelent you may use the DATA as a start point


    Cheers Bill

  • Bumped to Top.

    FYI, I was doing a QuickLOAD simulation for a 20 VarTarg with the 32gr Hornady V-max.

    The Top Five powders in terms of max velocity were,starting with highest velocity):

    Nitrochemie A/S 0300
    ADI AR 2207
    Alliant Reloder-10x
    Norma 200
    Alliant Reloder- 7
    Hodgdon H4227

    Assumptions: 58,000 max psi, 102% load density.

    Interestingly, Hodgdon H4198 was well down the list, even though this is equivalent to ADI AR 2207. I have found with other Hodgdon powders,Varget for example), it is better to use the ADI data. I spoke to QuickLOAD's creator about this and his reply was "the data Hodgdon supplies is not the best..."

    One can only hope that, someday, Lapua makes VarTarg cases. If I run a similation at 63,090 psi,the rating for Lapua 6.5x47), it shows 3897 fps being available from 19.0gr powder in a 26" bbl. DO NOT try this in Remington brass!!

    At that pressure level, FYI, ADI AR 2209 is the #1 rated powder.
