Two of these loads are powered by 53.5 grains of IMR 4350 CCI 250 primers, cases are Winchester, the only differences are the bullets. These being the 130 gr. Speer BTSP and the 130 gr. Nosler Partition.

The Speer BTSP is getting 3135 fps from 3 shots averaged.

The Nosler Partition is getting 3130 fps.

The third load uses AA3100 I am trying to burn up. Winchester cases, CCI 250 primers and 59.0 grs. of AA3100 topped with the Sierra 130 gr. BTSP. This load gives 3115 fps.

Temperatures today are over 100 degrees. The rifle is a Ruger M77, 22 inch barrel. I know the velocities are a bit high but the cases show no signs of high pressure, extract easily and all three bullets shoot into MOA.
