Fired my first Berger hunting bullet in anger (.264" 135 Classic) a couple weeks ago and killed a small muley buck at 197 yds out of my 264 WM at around 3100 fps. Downhill angle of around 30 deg. Long story short, it centerpunched a rib about 4" behind shoulder blade, then angled down and blew a 8"-10" zipper in the buck's belly, disemboweling him. It necessitated a second shot.
I too love their accuracy, but its terminal performance, or lack thereof, left me a bit cold.
