The 160 SGK in the 7RM on whitetail is a great match. I don't care for the 150 SGK in the same cart as they seem to not exit about as much as they do exit, but the 160 has just enough more to it to plow on through. The slightly lower MV with the 160 helps as well.
On small TX does, your current load couldn't get any better.
Good luck on your hunt.
