I run 147 ELDM in my 6.5 GAP at 3060fps and would not hesitate to use it on any of the larger plains game out a long way. 1650 ft-lbs at 600yds at 2150fps
No hesitation from 40-600+ yards with deer to elk and mostly bang flops or wobble flops every time. May make for nasty exit wounds on the smaller stuff though.
