ejection issues

My Rock River is throwing cases erratically, they all get out but only a few hit the catcher no matter where i move it. Would this be an extractor or ejector issue? It doesn't matter what recoil spring i use, tried 10,11,12 and still the same results.

David,

I'm going to bet it's a combination of both. Is your ejector still tight on your receiver? Do you still have the proper tension on your extractor?

Another question, did you recently change ammo and this problem started up?

No real change in loads but I think I found the issue, the ejector had a bur on it, took everything apart for a good cleaning, smoothed the bur off and it seems to be fine now. thanks for the response.
