I just returned from a South Carolina deer hunt where I took a 85 pound doe with the Max out of a Super 14 at 30 yards. The 180 XTP failed to expand...passed through on near side shoulder hit, exit through rear of rib cage. You might consider the 158 XTP if you'll be using your max for deer. The 180 probably will work OK at 35 Remington velocities or on tougher game (large boar hogs, etc).
