While we're comapring, what about Browning BAR Mark II?

The discussions about .223 vs. 308 have been great. I've been doing some research on a Browing BAR Mark II and wonder how it might stack up in this comparison. As semi-auto weapons go, and I have to note I live in the backwards state of CA, what do you smarty's think? How does a .300 Win BAR stack up, in you opinions, against my beloved mini? Thanks folks!
