No doubt...

but that little round was carrying the mail.

Some parallels I couldn't help but notice... at worst it is a pocket 30 Carbine, spiced with modern bullet technology. Except these bullets tend to tumble in gel like the 7.62xx39. I have seen plenty of examples of what that round does to people, cars houses and critters. At 200 yards it's loafing along about 1900 fps, but the FMJ tumbled when hitting this 2 1/2 gallon water junk and ripped it open.

Based on the video I think that's some of the 7.5's magic.
