The h1000 was my choice in my 7mm until last I started using hodgdon retumbo picked up some more speed and accuracy was just as good if not better. 160 accubond at 3120fps makes me smile
Ive also pretty much been using hodgdon powders for everything the last year and a half, you might want to give hodgdon retumbo a try Ive had good luck in my 7mm and 300win with it.
