Nice range day trip yesterday to shoot off some carry ammo that had been sitting around for a while. Brought my PM9 (primary carry gun) and my G17 (things going bump in the night gun). Shot off my HSTs and then some Federal target ammo - no issues and loads of good clean fun. Had a tube of the Brassmaxx I picked up cause it was cheap. Best I can say for it was it went bang. Shells ejected straight up from both guns. Not enough juice to lock the slide back on the PM9 (no I wasn't limping) AND I got my only ever FTF with my G17 (and I've put a lotta rounds through it) - round nosed into the ramp.
So it works but it's absolutely underpowered.
