Would advise to pay attention to the above warning. While i use once fired glock 40 brass, it is used in revolver with a fully supported chamber, and a semi with a "much more supported chamber than early/current glock".
If you hang on to your 45 acp brass through enough loadings, a buldge (wider than spec) can develop at the base that the normal resizing die does not reach. This is associated with the brass "shortening" after mulitple resizing, not neccessarily through over pressure loads. In a "tight" chamber this can cause difficulties.
