    Hi has anyone experience with H870 or H50BMG or AR2218 powders with regards to the .338 EDGE, .300RUM or the like?

    How do they compare to H1000/AR2217 with regards to velocity, E.S. and temperature sensitivity?

    H 870/H869 and H 50 BMG are to slow for the 338's .

    H 1000 or H4831 sc are best and both are extreme powders ( very low temperature
    sensitivity ).

    I find that in my 338 RUM H 4831sc burns cleaner than H 1000.

    My accuracy load with the 208 Amax is 106 grains H-870 at 3216 fps. When hunting I keep my bullets in my pockets so they are always a constant temp as at the range. H-870 is very temp sensitive.
