I just noticed this thread. Mind if I play?
I shot this with my M14 the other day. 1.2 MOA at 600 yards for 11 rounds with a 10 MPH crosswind. The first six rounds probably landed within 1/2 MOA. 169 grain SMK, 42.6 grains of IMR-4064, LC cases, Remington 9-1/2 primers.
That came from this beat up ol thing...
