I shoot all rifle and revolver brass until one of the three happens it either splits, the primmer pocket gets loose, or I loose the casing. However, pistol brass I only reload as long as it fits back into a gage block once it is resized. I have discovered after so many loads, varies with the quality of the brass, that all autos over time will allow the brass to belly like is commonly associated with Glocks but not to that extent. This bellying effect happens below where the resizing die can reach. When I had my first web blow out I noticed that the round was bellied so I started checking some rounds from other shooters at the range that also had web failures and all of their rounds were bellied too. Was it a coincidence or not, I don't know but I don know that since I started using a gage on all resized pistol rounds and toss those that no longer fit the gage I haven't had another web failure.
