On the left is the new style ejector, on the right the old style. The follower(tail) prevents over compressing the spring and twisting it up like the one on the right , one result of "enthusiastic" loading . Every one I've installed with a new spring and a .140 extractor ball, twelve of mine so far has solved the problem.
They're available directly from Savage Parts, the same P/Ns( ejector-spring) as before. AFAIK when you order new ejectors you get the new style, they've replaced the old.
