Im really going to like this rest. I shot the 45 6 times today at 50 yards and after i got everything set up and adjusted, It was wonderful to see the barrel steady and not rolling around. Im loading up right now to take the x-150 and the 45 to the NRA range and shoot it off their cement tables. Im going to start out with 100 yards right off the bat and then 150. Also going to pick up some 250Grain XTP sabots and give them a try in the x-150.
