Only thing I would add is to start at 90 gr of powder. My most accurate elk loads are 90-95 gr of BH 209. Plenty of power at that level and less kick, both for the the shoulder and pocketbook.

For the most part loose BH will be 15% more powerful than you pellet loads. In other words, if you normally shoot 110 grains of pellets, you only have to shoot about 95 gr of BH for the same power/velocity.
