I've never used Bergers on big game. And before I started guiding elk, deer, and sheep hunters I probably would have scoffed at the thought of shooting an elk with a Berger. I always used partitions myself. Been shooting 200 NPs out of a .300 win mag for a while now for deer and elk.

But the more I guide (usually 3-4 bull elk per year and a couple deer or sheep) the less I think it matters. Most of my clients aren't the typical campfire member/rifle loony that obsesses about this stuff year round. They buy a rifle some ammo and go hunting. Some of them have a bunch of money and hunt a bunch. And you know what they just kill stuff, IF it's hit marginally well or better.
