My hunting crew killed several caribou, bull elk, and deer with them last year. Mostly with 30 cal 168s from a 300 Win but 2 caribou with 115 VLDs from a 25-06. All shots were in the ribs and the results were that none of the bullets penetrated the critters to the skin on the opposite side. All of the bullets penetrated the close side and blew up which shredded the lungs and did a good job of killing the animals quickly. All of the shots were less than 300 yards save 1 5-point bull that was at ~400. That bullet put an entrance wound on the inside of the rib cage on the opposite side of the bull that was about the same diameter as a softball and got into the shoulder but never penetrated it. In the future, I'm planning to use Bergers for long range work but will stick to something tougher like Scirroco's, Accubonds, or Partitions for hunting in thick cover.
