H-4350 and Varget should work great.
I typically use the same powders that one would use in a rifle length barrel.
I may lean to ward the next fastest powder the rifle shooters use , but sometimes the same.
For example in 6.5-284's I use H-4350, and Hybrid 100V with 140's and in the 7mm Dakota I use Retumbo with 180's and H-1000 with the 160 class bullets.
