Any company that loads millions of rounds is statistically bound to load a squib.

Machines are good, but they aren't perfect.

I also would be interested to hear what Freedom's response is to your squib.

Glad you are OK and the gun is intact. I wager you will shoot slower for at least a little while.

Be safe.
