We have killed a handful of mule deer, elk, and oryx here in NM with the 156 EOL's from our PRC. We are getting right at 2900fps mv with our setup and we have no complaints. everything we have shot with this combination have been 1 shot kills. closest was 150 yard mule deer, furthest was 665 yard elk. All except the oryx have dropped at impact. Oryx was shot through the shoulder and destroyed the heard at 289 yards. That bull ran about 80 yards before tipping over. Most are tiny entrance wounds, but major internal damage. Only exits have been on close range mule deer.
