Reload or sell my Grendel upper?

[White Smoke]

Final results are in. All the problems I was having were attributed to a defective scope. It was sent back to the factory and was repaired. All is well now. The 120 TTSX is working best for me. 28.0 grains of H335 give me a 0.46" group at 2372 f/s. My prairie dog load for Arizona is a 90 grain Speer TNT, pushed by 31.0 grains of H335 at 2692 f/s and a 0.22" five-shot group at 100 yards!
