One dead on and one always to the left?
I'm getting two points of impact from two different loads at the same range. A Berger 168 grain VLD at 2780 FPS is impacting 3/10ths of a mil left if 175 grain SMKs but vertical the same. Same weapon system, same support (sand bags), same shooter. I could understand a higher or lower point of impact but what would cause it the lighter faster bullet to shift to the left? Could it be that the VLD hasn't stabilized at 100 meters? I get the exact same results every time.
