RIO7
Not my experience at around 100 degrees. No pressure signs but unreal velocities. In the 6.5x55 I was getting 3100 fps and no pressure signs with a load others thought was good. I dropped back 2.5 grains and am fine at 2,950 for the 129 grainers.
I got 3150 with the 130g Nosler accubond, about 5/8" group. Accuracy node at 2950, bug hole. This powder likes a mag primer.
