I was in the same boat but ended up going with 140 ttsx and they worked really well. don't think you will have much of an issue just depends on what your rifle will like more
My wife has taken 2 elk with her 7mm-08. One with Hornady Superformance 139 SST and on with Hornady Whitetail 139 Interlock. SST was 330 yards broadside cow and Interlock was ~80 yards in the neck on a bedded cow. Both elk were taken without issue. She is now shooting a 120 TTSX because the barrel decided it was no longer happy with previous ammo as the Superformance caused terrible powder fowling issues. The 7mm-08 is an excellent gun for shots at under 1/4 mile.
Yeah runnning 120 ttsx in my daughters. 2 one shot kills one at 40 one at 200. Never did run the 140s 120 just shot so dang well out of her compact barrel
