Disappointed by my most recent chrono session. I tried CCI#41 primers, 31.5 grains of H322, and a 70 grain BK. Velocity was only 3060 but vel was very uniform!! Looking at the case head, saw some smears so probably cannot go any higher.
100 grain Hornady spitzer, 32 grains LR, and CCI#41 primer, got me average of 2707 with some smears. The primers are difficult to seat so they flatten some before firing, they still appear to be right at the stopping point.
Was going to try some more but rain appeared.
My velocities at an earlier session was higher for some reason but with 7 1/2 primers. Will revisit this again
