I use 150 Gr. Hornady SSTs! But I am also not a neck shooter. I always place my shots 2 inches behind the from shoulder using the 308. Picks up the heart and the lungs and the exit is not that bad. If I loose much at all it is in the rib area on the exit side. With my 7MM Rem. Mag for longer ranges in Texas I use the Hornady 150 Gr. Viral Shok. I hold back about 4 inches behind the shoulder and let the effects of the bullet take the heart and lungs out! Therefore not damaging much meat.
