Primers will be Small Rifle. I have only used Rem 6.5 primers and for powders I used Varget with 69gn Nosler Competitions (.7-.9") and H4895 with 69gn Sierra MatchKings (.3's). I shot the 55gn Nosler Ballistic Tip ahead of W748 with great accuracy(.1-.2's). I also tried BLC(2) with the 69gn SMK; accuracy ran .3's.
As for suitable powders look at Reloader's Nest - a reloaders resource
and you can get a good idea of what everyone uses. There's about 46 different powders listed, so sift through and see what ya like. Check out the websites for the gunpowder companies and they have reloading data also.
Hope this helps. JohnnyK.
