Well, there may be issues with WWB ammo in their barrels, but I'm not sure the blame can entirely be placed on one type of "weak" ammunition. This is assuming the WWB they are referring to is the 100 round Value Pack 9mm 115 grain FMJ, and not the similar-but-different 50-round Winchester White Box 115 grain FMJ. I have not tested or chronographed the 50-round-box ammo, but I have shot a few boxes through my Glocks with no stoppages/problems.

I ran 4 different brands of target-type 115 grain FMJ 9mm ammo through a G17 and G17C last year, with the results listed below. Of the four, the WWB was the second most powerful, based on velocity.

----------------------

Factory "target" ammunition, caliber 9mm Luger, fired through a Glock 17 and 17C.

Temp: 68-70 degrees F, velocities measured 10 feet from the muzzle.

Each test string was 10 shots in about 90 seconds.
