Hello, oink. I'm curious if the labels on the boxes of Zeros you got displayed the bullet diameter. Regardless of the manufacturer, jacketed .44s virtually always come in .429 or .430. Wondering if yours were larger. Did you happen to measure them with a caliper?

I've used Zero's .357s for many years and they have given me outstanding service. I would be very surprised/disappointed to find any of theirs to be defective.

Regards,
Andy
