Trust me you don' t want to touch off a ULA chambered in anything larger than a 7 rem mag.....the 284 win I shot hammered like a 338 in fact the 338 was preferable...he(M Forbes) sells sandbag shells just for that reason. You don' t get a free lunch with the light weight...his stock design and recoil pad minimizes recoil to a degree but you still get wacked... hunting you would probably never notice it though.
