Increased demand is having its usual effects. For some, it means decreased QC standards. Even when QC is more optimal, increased production still means a greater number of overall rounds in which even acceptable failure rates can occur. I've had several examples of late, some more exciting than others. This example, from a range session today.
Blazer 40SW 165 FMJ, p/n 3589. ~5000rds acquired a couple of weeks ago. These three rounds were all in box #3 of the first case. The round on the left was fired in a stock gen3 G23, which went "fzzzzzzztttt" instead of bang. Bullet stayed seated in case mouth but increased OAL of cartridge. Stoppage cleared without issue. I expect to find more of these. (Primer on the right is also deformed, but not obvious in the photo.)
Availability has a quality all its own, but be careful out there folks.
