What make of rifle? Marlin, Winchester, Winchester clone?
It is a Winchester model 94 AE Trails End model, the extractor gets them about half way out and then lets go.
Thanks to everyone for replies.

I also think it is the extractor. Take a close look at it to make sure a piece hasn't broken off or if there is some crud in the top of the hook that is not letting it grab the rim properly. Also check that there is some spring pressure pushing it down properly and it is not just floating there.
