I recently had Moon rebarrel and true a fn spr action for me, and wow this thing will shoot. I tried to work up a load using 140 bergers and reloader 17 and it shot everything I tried well... very well. So I settled on 43.5 gr shooting at 2950 fps and took it out to my friends farm that has steel set up from 600 to 1000 yards and hit any thing I put my crosshairs on. This rifle made it very easy to hit small prairie dog targets at those ranges. Needless to say im very happy with the end product and the great and timely service I received from crescent customs, just want to give Moon a shout out for doing a outstanding job.
