I fired a 375 banded solid bullet today at 1020 yds and 2560 yds. The bullet is 6.5 cal. in length and weighs 397 gr. It was fired from a 13-6.5 gain twist barrel. It was dead calm, three shot group at 1020 was .6 moa. I then took it to 2560 yds, verticle despersion was 1/2 min or so. Thunderstorms were developing and the wind was blowing from every direction at 2-5 mph, I held the same point of aim and did not attempt to correct for it. I recovered one of these projos that had hit a clay/gravel bank at 2560. It had landed point first and looked similar to a drill bit. It is very obvious it was still spinning at a very high RPM. I had a buddy stationed in a safe location at 2500 yds at he reported a distinct sonic crack when it passed overhead. The bullet is the ZA 375 6.5 cal.
