Never expected this preformance from norinco ammo. 500 meters with my rem 700 VTR, I fired a shot it fell a few feet short of my 18x18"target so I started walking it in and cranking it up as I went till I got to 5moa and I hit a 4"three shot group in the middle. That was with 147gr norinco copper jacket lead core. I then switched over to advantage ammo doubletap loaded with 165gr nosler accubonds... Those fell 2' short and 2' to the left of the target. I would have thought a 165gr boattail in a hotter round would travel at least as flat if not flatter farther then a 147gr lead core spitzer??
