My experience exactly.I cant tell you the last time I had a non-firearm caused dud from mini mags.
Plus my green mountain barrel LOVES mini mags. So I dont shoot anything else.
I recently had a couple of rounds of Aguila that were bad. They wouldn't chamber in anything, including a S&W Model 18 revolver. It's hard to see from the photo, but the lead was pushed down over the mouth of the case. I contacted Aguila a few weeks ago and crickets.CCI, as has been stated numerous times...I'm having good luck with the Aguila 40grsuper extra.
