I have been loading 120gr Barnes ttsx for 5 years for my wife's browning x-bolt 7mm-08, 15 whitetail deer have been taken, all of the bullets exited and the deer drop like a ton of bricks. Average weight on the deer 120lbs-200lbs, does, to bucks at distances out to 300yds.
I use the load data provided by Barnes on the web site. My current load is with Varget powder and Chrono velocity of 3,005fps.
This is below max, but produces soft recoil and sub min groups.
