I stopped watching MAC videos after this....Although visually entertaining I highly suspect some of his videos are "edited" especially some of the gauntlet ones. that and he goes out of his way to explain what knife he uses to cut open the gel. I mean, in explicit detail down to the name, model, name of manufacturer. He's promoting it... and when someone goes out of their way to promote products then I find the integrity of the results in the videos questionable...

Besides, velocity is fine but how does that translate into effectiveness of the round in it's intended target? 9mm in a revolver? A short, snub nose revolver? I think it's been proven time & time again that a 9mm performs best in a barrel at least 3.5" of length. A snub nose 9mm revolver? Might as well get a 380...
