I have shot distance, but I have not shot distance with the Ms3 still attached to get a more accurate MV while shooting. I get a 0.5 mil (1.8") shift low at 100 yards with it attached. Can I expect the POI at distance to still be 1.8"s low or will it grow like group size? Yes dumb question, but want to know what to expect before I go shoot it. Thanks.
