Of course your problem with Hunter might have been seating depth or not being on a velocity node, in which case just switching powders isn't necessarily going to help.
This some barrels will show a distinct preference for certain bullets or powder but the bullet and how it is seated is no. 1 for me, powder type a distant second.
Work up to 58 or 59 grains H4831 with the 200 grain bullet. This is JB's "Loads that Work" and seems to be almost universal. Then tweak seating depth to establish a baseline.
Hunter should work but the above load has been tested and can let you know what accuracy level you can get or if your rifle just does not like that bullet.
