Greetings:
I have 150 units of this bullet.  I would like to work up a good coyote load for it.  Accuracy is key.  I see a lot of load for 75, 85, 100 etc.  Who has had experience with the Sierra 90HPBT Gameking?  Please share your thoughts.  I have some loaded with 57 grains of H4831sc and they group OK, but I think I can do better perhaps with a different powder and a lighter load.  Please advise.
Thanks,
Strikenmike
