Hornady Critical Defense Dud

Just got back from the range. I have zero experience with this ammo, but it's Hornady who I think of as a good name, and I haven't heard anything negative about it, but I had a dud round in a box of 25. 9mm, 115 grain. I tried re-chambering it a bunch of times, and then finally thought to look at it. The primer was dented from the striker hitting it over and over, but the primer didn't fire.

I still have seven I didn't shoot, so out of 18, 1 was a dud. That's an awful percentage. Is this common or did I get the 1 in a million bad ones?
