The Berger and Ballistic tip have nothing in common from how they initiate expansion, jacket thickness in the nose, shank and boat tail, nothing even remotely the same!!!
Seen a crap ton of elk shot through the shoulder with a plethora of bullets, I have yet to see a Berger not make it through. I've tried even, shot a cow elk at a stupid steep angle inside 300 with a 140 Berger, hit her dead center if the heaviest knuckle, she cart wheeled down hill to the truck dead, found the bullet in the hide half way up her neck, the front of her lungs and all the blood vessels going out her throat were hamburger. Watched a bull take a 300 gr through both shoulders, can't count how many 168's I've found under the hide after going through the shoulder, 165 matrix has cleaned the shoulder on many a bull, I hate shoulder shooting elk but that's 99% from bonded or mono bullets!!
