Continuing in the saga.
I loaded up 16 rounds of .313 pistol bullets ahead of 10 grains of IMR 7625. This should have produced about 1350 FPs. The day was cold. really cold. it was -8 F so the session was short. Good thing, too. There were no keyholes, but also no accuracy at 25 yards. The "pattern" had to be 15" and all over the paper. When I got home the bore was rough enough a cleaning patch would not pass. I switched to a brass brush. A few passes smoothed things out, so I conclude some leading must have occurred. Since the .312 jacket bullet grouped into about 2" @ 25 yards, these bullet must have stripped in the rifling or were too soft or both. This was a failed test. Onward to the next.
