Sweet! Thanks for the quick reply guys! Ya, most of my caps don't have the indention but some did. To test it, I took a dry bottle and capped it, then held it submerged in water for a couple minutes in my sun tea pitcher and watched for bubbles. No bubbles! Guess I was just worried that the gaskets weren't getting sealed against the bottles properly.

I've broken bottles before by capping too hard, usually my sign is if I see the indentation I'm capping too hard. The thing that sucks is it doesn't break then and there, usually the top of the bottle breaks off when cracking the bottle open to drink.

This is your best test. The indent is from pushing harder than the non-indent neither is a massive problem except for potentially breaking a bottle as some have mentioned.
If in doubt about whether they're capped submerging them and looking for bubbles is simply way to tell. You could always compare a few bottles with indents and without to be really sure their isn't an issue.
