Doing the exact math, a 422-grain bullet shot at 3300 feet/sec is 13,833 joules of kinetic energy (.5 * mass * speed*2 = energy) Right before hitting the targe

Doing the exact math, a 422-grain bullet shot at 3300 feet/sec is 13,833 joules of kinetic energy (.5 * mass * speed*2 = energy) Right before hitting the target it slowed down to 600 feet/sec, meaning it lost 97% of its kinetic energy during the flight.
