Ok so here is the set up first. The rifle is a R.E.P.R. with a Nightforce 20 moa scope base holding a USO SN3 3-17x44. Bipod is a Harris 6-9 with Larue QD Swivel mount, in 6" configuration. I had the rig sitting on top of the concrete shooting bench at the range (the ground was muddy and icy, I need a shooting mat) when some how it tipped over clock wise, impacting the right side of the scope including the windage turret (#3), the objective bell, and sunshade (it had been raining). It gouged all three locations through the anodizing and left some concrete residue that I wiped off. The only force of the impact was from the rotation of the bipod, only roughly 8 inches of travel. The next round at 300 yards impacted a few inches to the right of POA. Going back to 100 yards I milled it was impacting about .5 mills right. I pushed the windage knob .5 mills left and corrected the POA-POI difference. The group size seemed to not be affected. So I am wondering if such an impact to the scope will normally cause that much of a change in POI, or POA depending on how you look at it. Or should the equipment have stood up to such an impact? During installation all mounting hardware was torqued to specs with a torque wrench. I am also wondering if any damage could have been done to the turret adjustment internals? Some exercises will indicate any repeatability problems in the windage adjustments. Thanks for any input.
