I'm getting a synthetic stalker in the next couple months and I can't decide if I want the shorttrac .300WSM or longtrac 30-06. I'd imagine it's not going to be as much a tack driver as a bolt gun at 350-400 yards and further. Most shots will be on whitetail at 50-250 yards but I have had to pass some 350-450 yard shots when packing my .35 Marlin. I love the .300WSM in the bolt actions I have shot, but the 06 is a tried and true round. I am really just curious as to the accuracy I'm looking at in these two rounds in the BAR platform. It will also be used some on boar, elk, and perhaps black bear. Anything real heavy gets the call of my Marlin 1895G.
IMO the only thing the 300 WSM is going to dobetter than the 06(especially at the ranges you described)is suck more money from your wallet. If you plan to handload then this is probably a moot point though. If it were me though I would forget about the BAR and go with a good bolt rifle chambered in whatever you like.
