Yes, no 22 cal. Any other cal is fine.
Seriously though, give it to a fire department or something. Those ones don't have the 15 year life like the carbon fiber tanks (I'm pretty sure). They might have a use for them. Don't be too scared to push the pin, only poblem you'll have is the freezing tank, reg and whatever you're pushing the pin with.
