75.6-76.8 looks promicing to me. Maybe you could try different seating depths with those loads?

What helped me was to determine center of your group. Draw a center line though the group horizontally. From your bullseye, draw a centerline horizontally. Measure distance from bullseye to center of group. Write that number next to that group. Write those numbers down on a separate piece of paper [to eliminate confusion] and look @ the numbers. Worked for me anyway.
After that, be very careful here. Load different OAL's & record group size. Look very careful for pressure signs.
Have dinner reservations ready @ establishment of choice for some serious celebrating! Let us know how you do. Good Luck!

Have you tried different seating depths? Just wondering if you started with .05 jump or worked to it. I'm loading the 168 vlds with 78 grains of RE22 with .020 jump. Shoots excellent but there is room for improvement with my load.
