akbound..... is right about the recoil of a 40X chambered in 6.5x284, it would be nill.
Here is a 40X chambered in 300 WBY, built on a short, single shot action. Off the bench it can be shot easily with using the benchrest technique with full throttle loads. The weight, while not real heavy does damper felt recoil. It wears a Leupold 8.5x25x50 LR for seeing distant critters.
