I have gotten WELL sub-moa using that bullet out of IMR 4064, and Hodgdon BC-C(2) also (BC-C(2) started out as a military powder for the 7.62x51).
. . . just in case you didn't already know about them, though I'd bet my whiskers that you do.
Course, while I've got a few pounds of 4064, I've only got about a half-pound of BL-C2. I load for my gas gun (M1A) using that powder.
