Odd. A '30 caliber's is a 7.62 mm round. You would see this especially if an SKS or AK-47 was involved. I first learned it had a distinctive sound by watching Full Metal Jacket daily in the months before shipping out to MCRD San Diego, and then learned in person a little later in life. I find it strange that the term 30 caliber was used, the only time I've ever mentioned or heard 30 used in gun talk was when speaking of the 30-06, and there's no way one of these were used it it would have been very obvious. Just a weird thing to say in my opinion.
