Casey, my .270 gets 3100 fps with 150s using published RL-26 data. I can assure you it kicks very much 150 s from a 7mm Remington Magnum--because I have a 7mm RM of the same weight.
Neither is particularly annoying to me, but I have guided Eastern whitetail hunters who purchased a 7mm Remington Magnum to "reach out and touch" pronghorns and mule deer, leaving the .243 or .308 Winchester they use on whitetails back home. And they could not shoot their new 7mm very well.
