My daughter shoots the 120 TTXS out of her 7-08 700 youth rifle.She shot a 5x5 in NM with it. One shot thru the shoulders at 225 yards. Bull dropped on the spot and the bullet kept going.
I used it on a 3x3 buck in Dec here in CA. Shoulder shot, complete penetration and the buck went right down. Factory Barnes Vortex that do inch groups with light recoil from a 20in barrel.
