    Does anyone have data on loading 300 Win Mag (Not Short) using the new Hornady Superperformance powder?

    Nope, been looking myself. I compared some .300 wsm loads and win mag loads with the same powder and they seem to be well within 1 gr. I have though about working one up, but it seems the superformance is very specifically blended for certain cartridges so it's doubtful it will do any good other than satisfying curiosity.
