Looking at one problem box of WWB a Year or so ago, I found that the rounds weren't uniform in OAL, which could cause feed problems in some pistols. I also saw that while the shoulders of some of the case rims were squared off, some shoulders were rounded. I believe that lack of uniformity might be why some of my pistols experience FTX with the WWB 100 round Value-Packs... The 50 round White box rounds did seem much more uniform.
