Thread: H4381 vs H4381sc

  1. #1

    H4381 vs H4381sc

    evening all,
    this may be a silly question but i've had trouble grouping any boat tail bullet.
    So a friend helped me develop a load using H4381sc powder with a Hornady interlock 117g BTSP.
    However locally i cant get any H4831SC powder but i can get standard H4381 powder.
    Would there be much difference load wise?
    Hodgdon says they're physically the same powder???

    Matt Im using 4831 and the 117grn interlock in my 25-06. The only difference is in the load capacity I think, Ill be getting perhaps a 90% fill with the 4831. The short cut would have a lesser % in fill capacity. Ive just looked up the hodgdons site and they only list data for 4831, they dont list both. They say the short cut is the same but shorter grains to allow better meatering.

    I was lead to believe that this is the primary reason for SC over standard H4831..

    Why not shoot flat based bullets instead? Will stabilise faster as far as I understand due to greater drag around the base of the bullet

    im getting around an inch group atm but might have a play with powder to try and tighten it up. i didnt chorograph them. the best bit for me was i phoned a gun shop today and he has got two boxes at 16 a box.

    I was told by 2 other forum members the 117 btsp's give better groupings when they pushed them faster. Im getting 1/2" groups which Im delighted with as my cross hairs arent the thinnest and block the bull out at 100 yds..

    H4831 is just rebranded Aussie made AR 2213.
    Yes, the only difference between the long & short cut is the length if the grains.

    Cheers Sharkey

    Edit, Sorry I should have added its all short cut now so its just called H4831/AR2213. The SC has been dropped.
