If I was getting that kind of accuracy and killing power with a bullet at 190 yards there would not be any need for me to go looking further for a load to shoot....

I have shot the precision bullet silver lightening in 300 grain out of my Black Diamond XR and they shot excellent. The accuracy was outstanding. The rifle also shoots powerbelts all right, but I have not had a chance to harvest a deer with the rifle as the deer were most uncooperative this year....
