You maybe right. On all 3 of my savage actions I replaced the spring and ejector ball to the larger size .040".
I notice that during a slow extraction that the brass will come partly out of the chamber and then cock to the right when the neck clears and goes into the locking lug area. That is where it is either going to eject of drop back into the feed ramp.
If done quick enough then it will eject out of the action if not then I need to dig it out with my finger.
The ball goes under the extractor. Your problem is the ejector. Savage has a new ejector that has been out for a while now. It has a leg on it that goes down thru the spring which keeps the spring from bottoming out and weakening.
I just took a stripped bolthead the other day put new parts in it, installed it on a bolt, then headspaced a barrel onto an action. Matter of fact, bolt and action is the very first Savage I ever bought. It started life has a
22-250 now it sporting a 20" .223 HV barrel on it.
You can even make a Savage action eject a 6br round if you know what to do.
I've owned over 20 Savage rifles, probably closer to 30. I haven't kept up with them all but I bet all or most are still in service today.
We take them to Wyoming every year and shoot pdogs with them, they haven't let us down yet. One little thing I do know, mechanical things either break, wear down, or leave the factory faulty.
Mass produced anything does it a bad batch of something and before you know it, it's too late, the public has it and the companies get thrown under the bus without a chance to redeem themselves.
The internet is a fast and moving demon to ruin decent reputations.
