Jon, those sound like great results with the IMR-3031. I will try some in my friend's gun. He is a hunter, so I have ruled out the Scenar for his use but could you ell me the base to ogive dimension and the overall length for a couple of your bullets? I think we will end up using the Sierra 165 SP GameKing given his throating and the length of his magazine. I expect to try some next week with Varget but i will be looking for some 3031 to try.
