So I'll be on the market for a new Browning rifle in 308 later this year. I checked the rifles out (so far the long action only) and it seems that the main difference between these models is with the trigger and magazines. AB3 uses box, staggered, partially metal magazine and X-Bolt utilizes the rotary, plastic magazine. Trigger appears to be much nicer on X-Bolt, since AB3 employs a plastic one. AB3's bolt is a bit bigger. Otherwise the action looks nearly identical. What's your take on these rifles? Thanks.
