My fiancee hadn't watched Full Metal Jacket before and part of the prenuptual is that she had to, so we were watching it last night. I got to looking at Animal Mother's linked ammo that was hanging all over him and I noticed, it looked awefully large for 7.62x51 (.308). Expecially the 5 rounds he had linked and strapped to the back of his helmet. It almost looked like it was long enough to be .30-06! Through parts of the movie the ammo on his chest looked large, but sometimes it look more like .308. the ammo on his helmet definitely looked too big. Anyone with the movie want to research this and tell me what you think?
