I've repeatedly had issues with the 140 6.5mm VLD blowing up and not penetrating bone at a started velocity of 2880 FPS and distances from "close range" to about 500 yards. Maybe a bit further but I am not recalling right now. Elk shoulders have normally been involved though. I can't deny that.

Even when not, berger's killing effectiveness has been grossly exaggerated, IME. They have normally worked fine when put behind the shoulder, but no better or quicker than regular C&Cs.

That's just my experience and I am sure the usual suspects will tell me I am full of it, have too small a sample or whatever other excuse they can come up with to argue that they're experience means more than mine. Carry on.
