Just a tip on your load development, if it doesn't shoot any of the loads you try, then use a regular large rifle primer, I had to do this with my 300 win and H1000, shoots lights out.It took months! Now I just hope my rifle likes it! 300 Win Mag loading 212 eldx. 75gr seems to be the sweet spot for most guys.
