Browning's are good guns that usually shoot well. The A Bolt is a bit different than the X Bolt. I had an X Bolt in 300 WSM that shot fine. I had zero issues with feeding and performance was good. I liked the trigger and the short bolt lift. It had a polymer mag that functioned fine, but some folks just don't like plastic on rifles. The X Bolt styling is Euro-ish whereas the A Bolt is more typical American. The X Bolt is rather lightweight, which may be good or bad depending on caliber and your personal preference.
