The Marlins are GREAT rifles for the price. You can't go wrong with the Marlin X7. I had a Marlin XL7 in .270 and it shot just as good as other rifles costing hundreds more. It also comes equipped with their version of the Accutrigger and a Weaver type scope base. I haven't had experience with the Savage Axis so I can't comment on that.
Sometimes you earthlings REALLY amaze me!
