I was always cautioned by various older female relatives to always use new 
jars when pressure canning. I've had enough used jars break while in a 
boiling water bath that I've stuck with their advice and haven't had a 
pressure-related breakage yet.

I suppose it depends on how much pressure you're using, as well as how 
well the jars are made.
