    Hodgdon Superperformance .243

    Morning All,

    Just got a tub of H Superperformance and looking to work up a load using 85gr Gameking/Partitions in .243.

    Anybody got any experience with loads with this powder?

    Will post up results when they are in!


    Cheers

    Superformance powder has misled so many people, it is not the powder used in superformance ammunition as many people think, the powder used in superformance ammo is blended to suit the load its used in, so what you get in the tin is quite differant. The only data I have managed to find for it is a .243 load using a 75g jacketed bullet, this is in the latest lee modern reloading book page 221 Start load is 45g max 49g

    Burn rate is between H4831 and RL 22.....so should work with 90/95 gr heads in 42-46 grain range.

    Will load up some over next few weeks along with some 85gr GKs
