Man I really want to hunt bison. A dream of mine for some time now. I've even already purpose built a rifle, 35 Whelen Ackley Imp.

That aside, I used to own and load for 30-06 but no more. I always used 180gr Nosler Partitions over full cases of H431 for elk and deer. I hesitate to share the load I shot because it was well above conventional published data, but if you are curious look for a book by Bob Hagel titled "Game Loads and Practical Ballistics for the American Hunter". The load I used is published there.
