Has anybody ever heard of a load, or worked up a load for the 300 WinMag using H5010? Seems possible, maybe a tad slow, but with heavy bullets it should work. Compressed charges most likely.
 
That is what I was thinking, real heavy bullets, not the best powder but good for fire forming for a better powder.
 
I think you will find it very dirty too.
Slow powders like 5010 want to be at pressure to burn correctly.
 
I STILL HAVE A COUPLE CANS OF H-570 (thats hodgdons H570). and its too slow. if it was still produced,. it would be about same burn rate as H-870. have used H-4831/H-450 and H4350 IN my .300 win mag for years./ accurate and clean. shoot 220 grain hornady and would move up to 250 grainers, if i could find them. there,i might get away with the H-570, BUT THINK IT WOULD BE A REALLY COMPRESSED LOAD..POPS
