MY Lyman 48th Edition Reloading handbook lists the 75 gr. Hornady A-Max #22792 bullet. With Varget powder, suggested starting grains is 23.0 @ 2606 fps and max @ 25.6 gr. @ 2843 fps. It also indicates Varget as the most potentially accurate powder for this bullet. I don't know what twist rate you are shooting, but if you have a slow twist (i.e. 12"-14") barrel, there is a chance this bullet may not stabilize well. A faster twist ( 7"-9") is usually recommended.
