This was 325gr hollowpoint. We have watermelon shoot every summer. In the past we've used M193 55gr .223 round, which yields an impressive "explosion" with melon pieces flying around. However, it is nothing compared to Beowulf. As you saw on the video, the melon just about vaporizes. There are no individual pieces, just spray and mist. This was somewhat unexpected, I thought that the .50 cal bullet would just punch a neat hole and go straight through. I had my .223 AR as a backup with us but we didn't end up using it... I guess that it must be the pressure wave of the 325gr slug that causes the melon to blow up that spectacularly. Btw, we also tried shooting other objects, such as pressure treated wood and logs. However, we just couldn't find anything that would have challenged Beowulf. No matter how thick a log we tried, the .50 cal round went straight through.
