    Hey guys,

    somehow i wound up with a pound of IMR 4007 SSC, a powder i'm not truly familar with. looked over the load data at Hodgdon.com and found data for .308, a cartridge for which i need to work up loads anyway.

    was wondering if anyone here had ever used 4007 SSC in .308 and what kind of results they had. sort of trying to figure out if i should set it aside and or sell(it's unopened)/give it to someone who has a better use for it and buy a pound of Varget, IMR 4895 etc. or if i should just open it up and try it out with the Hodgdon data.

    thak you for your time and advice.

    I have not used it, but IMO, it appears a bit slow burning for 308. It's better in the short mags and varmint cartridges.
    It will work with heavier 308 bullets, but is not ideal, according to the Hodgdon data.
    Save it or sell it, if you do not have other rounds that work better with it.

    IMR says 4007 is a "Super Short granulated powder with a burn speed that falls between 4320 and 4350". If that's true, it's burn rate is ideal for heavier bullets, like the 180 grainers. A bit slow for the lighter stuff.

    Didn't have good luck with 150 gr bullets in .308 with IMR-4007SSC.Accuracy was very poor. However, it shoots very well in my .243.

    since there are a few comments on bullet weight..

    I'd be working up loads for 175gr SMKs since that what i have a supply of at the moment.

    thank you for the info/advice, please keep it coming :)
