I shot the Kimber this morning with Reloader 26, new Nosler brass, Federal 210 match primers and the 160 Accubond.
Velocity measured by LabRadar.
60.0 gr averaged 2935fps, .6 MOA
60.5 gr averaged 2982fps, .74 MOA
61.0 gr averaged 2997fps, .68 MOA
61.5 gr averaged 3046 fps, .3 MOA
Obviously the last load is too hot even though I had no traditional signs of pressure. Bolt handle lifted easily, brass extracted easily, but I have no intention of making the Ackley into a 7mm Remington Magnum. Pity, considering the accuracy with that load.
Temperature was 12 degrees all groups were three shots.
