Actually, when I was using it, it wasn't feeding properly and therefore not extracting. Sorry, I should've been clearer. It would bend the cartridge case like a tube of toothpaste.
I could see weak follower spring make it feed poorly, shouldn't affect extraction.
Make certain your extractor moves freely, has a good edge (to grab rim), and it's spring is strong. Another good place to look would be the well beside the chamber the extractor fits into, make sure it's not full of crud.
