Velocity/Expansion

I've heard somewhere that one of the problems with .300 Whisper/Fireball is that velocities were too low for adequate bullet performance. Does anyone have any hard data on this. For example, how about a Sierra 220 BTHP, what's minimal terminal velocity for adequate expansion? For that matter, what's considered adequate expansion?
