I have looked everywhere for load data on .300WSM using 178gr. Hornady ELD-X bullets and H1000 powder. Does anyone have anything that can help me?? Thx!!
If you really wanna try h1000 I'd start at 78gr and work up from there. That should be a fine starting point but I'd contact hornady and they may be able to save you some time.
Hodgdon doesn't even list H1000 as a recommend powder until you hit 200gr. It's probably going to be slow and dirty. H4831 is probably going to be a little on the slow side too, but would work all right. H4350 would probably be your best bet.
