Re: 5010 data

Just acquired some IMR 5010. I looked up some old posts, but I am still looking for load data for 375 H&H, 338 WM, 8mm Rem Mag, and 300WM. You guys were good for some 7mm STW data. How 'bout some data for these other cartridges?



Works well for 7mm STW w/160 grain bullet due to overbore. Too slow for others you list.

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.
