I have an r15 (22") and 3x12x42 m223 scope. I whipped up some surprisingly accurate 55vmax loads pushed with Benchmark (.2" 3 shots 100yd) and my chrony's averaging 3250fps, but the elevation markings aren't very close to what it should be. At 400 my scope is set 350ish, etc. Is the velocity claim on the scope turret (55vmax @3240) correct? Am i outrunning most factory ammo in 55gn bullets? Considering that Nikon probably based their adjustments on box ammo. Any feedback is appreciated.
