After reading all this stuff about the new box, I just had to go out and open one of the new 3-pack of 150 7mm's that came in the other day.
Amazingly enough, it opened really easily to the same technique that opened other boxes of bullets over the years: Slicing the paper over any place that looked like it covers a cardboard flap. Took about 10 seconds.
It went back together even quicker. It ain't a Rubik's Cube.
