The all time best semi auto hunting rifle is a Remington 7600 Pump
The BAR's are ok, but most are on the heavy side, accuracy can range from good, to worse. Do you love cleaning overly complicated guns? Do you reload, if so, you'll very likely need small base dies to ensure function. If you absolutely have to have a semi, I'd go BAR, or Benelli. The 7600 is better then both, and has the Fudd factor in spades. Also probably wont be on the Liberals list of hatred.
The 7600 triggers, can be tuned pretty nice as well, try tuning a semi's trigger.
Oh ps, if you still can't tell what I think, get a 7600.
