Finding the right balance between speed, spine, arrow weight, KE, and momentum?

That weight and speed will have plenty of energy to kill anything you would hunt in Montana at reasonable range. Going to a 340 spine is probably going to increase your accuracy. 2 blade coc head will also increase penetration a bit. Not that you need it.

Your bow's IBO speed isn't that bad @ 310fps.  The limiting factor is the 27 inch draw. 

The Magnus BH's are good!  I used to shoot them in 125gr version before I switched to 150gr BH.
