    Nobel type SP-83 powder???

    Hey all,
    I recently purchased a 4 pound box of HP-38 powder from a fella for $75 Canadian (here that is amazing, you probably get powder way cheaper down in the land of freedom)!

    I have the opportunity to purchase some other powder, the box says (Nobel type SP-83)from the same fella...
    I havenít been able to find any data on this powder at all.
    The fella tells me that it is the same as w231 and the HP-38 but has never used it himself. I donít want to use this without confirmation.
    Does anyone have any knowledge that they would be willing to share?
    Thanks in advance

    It is definitely SP-83.
    I have a picture of the box but cannot for the life of me remember how to post pictures here.

    Thanks for the link!
    After looking at the link, I am under the impression that they do not make this powder any more... or if the do it has been Redesignated with a different name.

    also http://www.tiropratico.com/ammunition/menu/index.htm Sweep across the top to the caliber range and use the drop down menu to dial it in. I've gotten much information here about Vectan and Nobel powders.

    Here is a burn rate chart http://www.tiropratico.com/htm/tabel...lveri_2011.htm

    HP-38, if it is similar would indicate a burn rate near BA 9.5. I don't find any information for a powder listing like yours.

    I didn't find any listing of that type of powder, either. Can you post a picture of that can? I use Vectan powder and have had to go to several alternate sources overseas for information some of it in either Italian, Spanish or French. One site in German.

    Hey guys, thanks all for your help!
    I was talking to a friend of mine that works in a ballistics lab.
    I finally found an obscure list of loads for this powder:
    9mm. 115gr jacketed max load 6.0 gr 1100fps
    .38 spec. 148gr lwc max load. 5.3 gr. 850fps
    .45acp. 200 gr Lswc. Max load 7.3 gr. 825fps

    So we compared these loads and velocity to known powder loads and found that 800X is quite close.
    I have loaded up some 800x 12g 1oz slug loads and identical loads in the SP-83!
    We will try them out in the lab and see how they compare in reality!
    Stay tuned!
