Well, I noided out and decided to re-cap about half of the batch with misc caps I had laying around. It's definitely the caps, because I just used about 3 different brands that capped beautifully for the "re-cap". When I popped the silver caps they did hiss a little (impressive after only being bottled 3 hours ago), so I'm assuming they sealed. They likely would have been fine, but I don't like taking chances with my beer. I also noticed that when I crimped these caps they gave me a little resistance, which I've never noticed with my bench capper. The replacement caps didn't have any resistance at all. I left 3 bottles (including the one in the photo, which was the worst of them all) to see how they carb up. I also tried to see if they were leaking by turning them upside down, but they didn't. If the "test" bottles turn out fine I'll keep using them. I held one of these caps up against one of my other misc caps, and they look like they are a little smaller.
Thanks for the replies friends. After bottling over 2000 bottles in the last year or more I would think I experienced everything, but you always learn something new!
