Another solid instructional piece! I think I heard one mag explode when it hit the deck.
I hope not---all but one of those were practice magazines--one solid chunk of weighted plastic with a bullet-form at the top. (The real mag had orange snap-caps in it. And like an idiot, the first time I tried to explain "bullets forward" I was using the wrong mag, so you couldn't tell what I meant AT ALL.)
I did have one time when the reload mag bounced completely out of the ROOM. (I'm doing these videos in my martial arts practice hall, so I have mats down over gymnastic foam.) I was showing a reload while transitioning and the turn gave the bounce just enough energy to go flying sideways---and it ended up making it off the mats and clear through the doorway.
That whole sequence didn't make it into the video, which is probably good because I couldn't stop laughing.
