A few years ago I shot two cow elk with a 120 gr TTSX out of a 7mm-08 at roughly 125-150 yards. One cow hit the ground and slid about 20-25 yards downhill to her final resting place. The other cow, took the first bullet, stood still then took a second bullet and stumbled backwards about 5 yards into a downed tree top.
I'd have zero concerns using your proposed load. Good luck!!!
