I bought 100 pack of CCI number #11 caps last year, and I think I might have some Winchesters from the year before. Anyway, as hunting season gets closer, I'm wondering if these are still good or if I should buy another pack. I've had some old caps that didn't work at all, so I wasn't sure how long they usually last.

I purchase 20 tins at a time. And they last for years. I am sure the caps are good.

The only way that they might not be good is if they got wet for some reason.

Nope, never got wet. Have been stored in a room temperature environment their whole life, so I guess they should be good. I just wanted to make sure.

I have RWS #11 caps I bought back when the were 10 dollars a roll at a booth at the National championships at Friendship IN and the still work just fine.

They should still be good!
