Rem 700 ejection problem

So, I've had my Remington 700 .223 for 15 years now and it's been a very reliable target gun
Last year it developed ejection problems, where about 20% of the fired cases would exit the chamber then drop down onto the magazine instead of flying out sideways. This is a real PITA in practical comps!
A few months ago I had a new barrel fitted (the original Remington one had lasted for 15,000 rounds, not bad) and the problem persists.
I have fitted a new extractor circlip and new ejector spring and this has made no difference.
The cases are once fired R-P, full length resized. I don't want to change these as I have a ton to use up.
I know I could have a Sako extractor fitted, but this would mean another lengthy wait (and fee) at the proof house.
Can anyone explain why a previously reliable gun should behave like this? I'm baffled.

I can only guess something has worn after those 15k rounds. I have seen a little spur ( no idea the proper term ) inside the reciever opposite the ejection opening wear down - as you withdraw the bolt it catches one side of the case and flips it toward the ejection opening.
Does your rifle have one of these ?

The 700 bolt has the extractor & ejector in the bolt body itself...

Usually Remington's have a massively strong ejector-pin spring - too strong. Is the ejector-plunger nice and free if you work it in and out? They can seize up with brass and crud getting down there. Sounds as though it might be sticking occasionally.

I take it you've done the first step of dismantling the bolt, giving it a good clean out, lube and reassembly?

Unfortunately, that won't access the ejector-plunger - which appears to be the problem.

Yes I have stripped the bolt, cleaned and lubricated as appropriate.
I think the problem is that the case slips out of the extractor claw and pings sideways in the locking area so the ejector spring can't do it's job properly. What I don't understand is why it's started doing it now and why replacing the relevant parts hasn't fixed it.
I've heard from other sources that the ejector spring can be too strong and cause this to happen. As I now have a spare spring I'm going to try making it weaker to see if that helps. I will report back.

Yes it will, the ejector plunger is mounted in the bolt face.

I don't know but I've just bought a bore scope so I will have a look, thanks.

You need a bore scope to look inside the receiver wall?
