and a single .30 cal. bullet can destroy a sandbagged position, (re: Saving Private Ryan, Enemy At The Gates)

I saw and enjoyed both movies,but I don't understand your reference.

In Saving Private Ryan, during the landing, the Tom Hanks character sends his sharpshooter, Scripture quoting, left-handed, so he has to reach over the top of the receiver to work the bolt, played by Barry Pepper, to "put suppressing fire" on a sandbagged MG-42 emplacement. The Pepper character tags the gunner and the a-gunner, and two more rounds from his .03-A3 collapses the entire pile of bags. Nice, satisfying, but hardly even remotely real. Real sandbags stop bullets, that's why they are there. Bullets make a .308 diameter hole, that's less then your pinky, in the burlap cloth, and can burrow in another foot or so before stopping. They do not explode, although a .30-06 bullet hitting a slab of meat might make you think they do.
