Based on my extensive research (of shooting everything I could find as a teenager), an open pornography magazine will not cause even a frangible (Glaser Safety Slugs or sintered copper and tin powder training rounds) to disintegrate. Heck they will pass though drywall sometimes.
However a phonebook (Google it) will stop FMJ 9mm ACP. While 308 will penetrate the phone book and the tree trunk it was tied to.
My ridiculous hypothesis of it being a low penetration weapon designed for time travelers to leave no trace when traveling to the 1942-1957 time period when the M3 was still in use was a bit of a stretch.
However Having a weapon loaded with non penetration rounds for home defence is the American Way, despite a fully automatic SMG being a comically poor choice.
Paper is surprisingly dense. Frangible rounds don’t require steel plates to break up. Note the ballistic gel part og the comment.

Either way, whatever slug he was using would be hilariously underpowered for anything other than tearing paper.
Having a target round of any sort loaded with the gun sitting on the rack seems odd and somehow an American thing.
