Almost all CRF rifles will do this and it is not a problem. The term CRF is confusing. All rifles, PF and CRF will "FEED" into the chamber equally well. It is with extraction and ejection where CRF rifles have an advantage, especially when rifles or ammo are filthy or the rifle has been abused beyond what most people would do.
If I were to drop my rifle out of a boat in Alaska and have to fish it out of the mud and fire 2-3 quick shots to stop a bear charge I'd want a CRF rifle. Otherwise there simply ain't much difference. Any rifle will feed equally well upside down or from any other angle.
I think found the part you are talking about.

I'd like to know more. I've never seen a Savage with a blade ejector, all have been a spring loaded button in the boltface. Is this something available just on certain models? Can any rifle be fitted, you'd have to replace more than the boltface. There would also have to be some milling on the receiver to also install an ejector.
