A few days ago I was able to retrieve a pretty good amount of once fired .40 S&W brass after a couple guys shot and left it at the range (I always appreciate such generosity :thumbsup. All the brass was shot through two guns, an M&P and a Glock. After cleaning the brass I was sizing it and found a few cases that were really stiff in the sizing die; they were all Aquila brass. Closer examination revealed that my RCBS carbide die had squeezed a ring of brass right down to the case head (see picture). I removed all the Aquila brass (8 pieces) and set them aside as junk. When I put a caliper on the case head area later, they measured from .427 for the best and up to .431 for the worst. SAAMI specs give a max of .424 so they are all obviously junk now. The only reason I mention it is because the other Winchester and Remington brass from these two guns was all fine, and the ammunition was seemingly all factory (factory boxes). This is not a case of Glocked brass necessarily, but it seems the Aquila brass might be a bit soft? Anybody ever reload Aquila brass? This is the first that I have come across any here in NW Iowa, and it does not seem good at the moment.
