Yesterday I was loading a bunch of 9mm and I was using Win. head stamps, with exception to one single W-W head stamp. Twice throughout my years of reloading I've had neck tension issues with 9mm brass, both time it was W-W head stamp. Although it's not a problem for me because I check neck tension as I seat bullets, I do however wonder why WW brass has been the culprit in both instances. Oh, I did encounter a similar neck tension issue with WW 38 special a couple years ago too.
