I just read in the Q&A section of CZ Forum that the WWB in 100 round boxes have a different extractor groove than is found in the 50 round boxes and can cause problems in individual guns, regardless of make or model. I hope no one minds mentioning another forum, but there is a pretty good Q&A about quality inexpensive ammo.
Now I'll try my XD with WWB in the 50 round box and see if it has any problems!
