Ryan: What distance are you shooting?
FYI, 1-2 duds per bulk box would be a deal killer for me. Glad you solved the problem. Ammo should be 100% reliable. I've only had one similar experience with a case of CCI mini-mags that varied significantly in velocity. Sent a few back to CCI for testing. The said neck tension was the culprit and sent me a new case of ammo.
