Major,
I like you’re thinking and using a 150 grain bullet was something I had in the back of my head already but I figured I was long winded enough with my original post.
I researched what the recoil difference would be between the 130 & 150 grain bullets and found Chuck Hawk's charts.

The recoil energy goes from 16.5 to 17.0 or increases by only 3%. But like you said it slows down the velocity to a much more manageable 2850 FPS vs. 3100 FPS for the 130 grain bullet.
I never thought of the reduced coil ammo. I will look into that.
