Does your Ruger Mark II rifle fail to eject (i.e. the ejector doesn't come up in time) if you run the bolt really fast? (Don't try this with live ammo at home on my account!)
 
I have never had a problem cycling either the 338 MK ll that I own or the 30 06 that I used to own although I don't recall running the bolt "really fast"
 
Never a problem with any of mine, fast or slow. Check the spring to see if it's broken or weak, or maybe things are just dirty and need a cleaning? The ejector should pop up with good spring pressure, or at least mine do.

Fast as I can work my .375 H&H, it always ejects, even really trying to go like a banshee. I read the article you likely had this sparked by too, he saw an example with a dirty / gummed up ejector I'm sure of it. That would slow it down.

Don Heath said six out of seven Mk II RSMs failed to eject when run really fast. That rattled me so I wanted to find out whether anyone here had experienced similar things. Running snap caps through my .375 RSM as fast as I could, I couldn't get it to fail to eject. Also, I've got a McMillan on order for a boat paddle .338 that I have designs on as a wilderness bear defense gun instead of a Marlin guide gun. The .338 is already on the fence as I have kind of settled into .375 H&H for the most part, but maybe I'll just let it ride, get the new stock and see.

This thread states that even commercial Mausers have pivoting ejectors, and my CZ527 has a pivoting ejector too. Dunno about the CZ 550 in .375 H&H etc. Same? Maybe I should just stress test the rifles as fast as I can, tweak whatever needs tweaking and use in good faith...

Thanks for input everyone!

If I recall correctly, in his book "Rifles for Africa", Gregor Woods made the same comments about the Ruger RSM, but limited the alleged problem to those chambered in .416 Rigby -- citing the wider case as the genesis of the problem in that particular rifle. And he also indicated, I believe, that the problem was corrected once Ruger became aware of it.

I've got two Ruger RSMs that definitely do not have this problem, at least I can't get it to happen -- but one is a .375 H&H and the other is a .458 Lott, both of which use the standard belted mag cartridge with. I wish I could comment on the .416, but A-Zone has thus far refused to sell his to me (some friend, huh? :p), so I'll have to wait and see if he chimes in here...
 
At the worst, if you found an example that does exhibit that curious issue, you could easily polish the ejector and its groove, or even fit a stronger spring very easily. Like you've mentioned, many good CRFs use articulated / pivoting ejector blades, so it's definitely not a faulty design, just sticky blades it seems he encountered. I've quoted that article in the past as well, with regards to Remingtons, and I now believe his accounts to be a little suspect. I'm still no Remington fan but there seemed rather remarkable amounts of failures there in a very short period of time. I've used an RSM and other rifles in the same place that was written and have experienced no such excitement.
