I just discovered something today I thought I should pass on.
My Rem 722 would not eject the cases properly. Extraction was not a problem, but ejecting the case was.
I first cleaned the bolt face and made sure the spring for the ejection plunger was not stuck of broken. Then I looked at the position of the little circular ejection clip which is in a recess along the inside of the bolt face along the rim. The clip looked in good condition. I had noticed that the case were being ejected NOT toward the open side of the receiver, but more in an upward direction, which was wrong. It occurred to me that perhaps the ejection clip was in the wrong position relative to the open side of the receiver. I took a nail and without removing the clip, slid it around to a different position. Problem solved; the cases are now ejected toward to the open side of the receiver.
The problem was not the clip, or the spring, but the POSITION of the clip.
