155gr Amax, 308 pushing them 2875fps muzzle velocity, range 385yds, drilled through 5/16" mild steel gong. I assume that is enough to break the skin on an animal.
If you want massive damage and spectacular exit wounds (and some spectacular bruising), the Amax will do it when used at closer ranges. Just don't expect to get Texas type penetration.
Broadside, no shoulders, under 2900fps impact velocity - PUFF.
For longer distances, they become ideal offering controlled expansion at lower velocities.
