i am thinking about upgrading from my Remington 7400 semi auto.

Any opinions on the "best" semi out there" Accuracy and no jambing are paramount.

I am smitten with the Browning BAR and the Benelli R1. The downside (for me) on the R1 is it is only available in 30-06 and 300 calibers. I am partial to the 270 Win. I wouldn't grip with the 06' though.
