Like your rifle, my Black Diamond XR shoots roundball very well. I never push them as hard as you do, but that is some good shooting. And the Shockwaves out of the BD are just deadly. I was shooting them at 150 yards, sitting in a lawn chair, off shooting sticks into a paper plate. I had to find the drop mind you, but once that was discovered.. I could hit that plate with ease.

The BD is just a good rifle. Granted its old technology but it sure shoots well.
