My buddy shot a 150 class whitetail on a hunt with the 150 grain Barnes lauched from a 300 RUM. The deer spun in a circle and dropped. It had an 1.5" exit wound and the bullet did not damage much meat. I would say it is a good round for whitetails at high velocities because they go down fast but the bullet does not seem to cause the extensive meat damage that the rapid expansion bullets do.
