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.
