I shot this a couple weeks ago with my GAP-10 chambered in 308. All of my groups were pretty tight but this one was by far the tightest. This is a 5-shot group fired at 100 yards. It measured 0.172 center-to-center.
The load was: 168g AMAX, freshly annealed Lapua brass, CCI 200 primers, 44.0g Varget, and a COAL of 2.810. All were fed from the magazine. The average MV was 2621.
