Saw that. Notice the 5.56 tumbling? I know there were early on questions as to the suitability of the bullets available, and also that there were some experiments in twist vs. stability. What were the final compromises made, and for a 1:9 twist, what is the best weight bullet? But that is a bit off topic. The orange juice shot is impressve, but the shot of the 22 cavity more so. The photographic setup had to be tedious, but a spectacular result.
I think the 55 gr. is what Ghostrider was trying to say about the 5.56. It tumbles after it hits, which in my book isn't necessarily a bad thing, unless you are trying to line up several people in a row. It still did it's job.
While hunting in light to moderate brush, the 5.56 is not as reliable as some other heavier rounds. Besides that, the unpredictable tumble is advantageous like has already been mentioned.
Roger. Actually, I didn't know an M193 would yaw in only the three inches through an orange. Learn something new every day.
