Steve, There is such a thing as IMR 5010, which is a very slow, very chunky milsurp powder. It works very well in .30-06 and similar cartridges with heavy cast bullets seated well into the rifling, particularly if you want to hold velocity between 1,750fps - 1,850fps. Burning efficiency is enhanced when a small amount of filler (as little as .3cc of Grex or powdered bran) and mag. primers are used. Btw, the loading data that came with my powder was for .300Win mag., et al. ...Maven

Are you sure it isn't H-5010?

And it really isn't the best powder for any of the calibers you listed.
