Controlled round feed 1rd at a time?

Sharkbit,
If you take a look at the extractor on most if not all current "controlled round feed" bolt actions, you will see that the front most portion has been cut at an angle which allows for the extractor to slip over the case head when the bolt is closed.
Not knowing your rifle, but going by your comment that the bolt will close on a chambered round, "without any resistance" I suspect that the face of your extractor has also be beveled.
Typically, if this has not been done the bolt will not close as the face of the extractor is blunt and simply butts into the case head and will not spring over the head and into the extractor groove.
The bolt closing on a chamber round with little to no resistance has been normal with most rifles for years, even if they are said to be controlled round feeds.
In reality and in most modern controlled round feed rifles, they differ mainly in cartridges pushed from a non-controlled round magazine, they simple lay on the remaining rounds or follower and if the rifle should be turned on it's side of upside down the cartridge would drop free of the rifle.
On a controlled round action, this should not happen as the head of the cartridge slips behind the extractor as the cartridge is pushed from the magazine by the bolt.
Now days, with most bolt actions, both styles will allow the bolt to close on a chambered round, making no difference if it comes from the magazine or is simply laid on the follower or pushed into the chamber.
