In this I will defer to Parashooter's definition and interpretation, seems reasonable and logical in the way it is presented.

As per para's explanation I think fits the bill on how the lee system functions as I was always taught/told that the claw can be broken if you popped a round into the chamber then slammed the bolt shut on it if the round had not risen from the mag.
In regards to Post #5 I know of this incident (@ 2 years) a shooter down here suffered this extremis with his Mosin where a round was cycled up the spout and for reasons unknown at the time and still are the bolt was withdrawn leaving a live in the chamber and the following round cycled with vigor detonating the primer of the chambered round.
The chambered rounds projectile left the muzzle striking @30m from the rifle, part of the case and the round behind it were blown out of the action, the shooter suffered NLT injuries to their I think Rt hand the fore stock was wrecked thankfully the bolt stayed in the action and not through the shooters face the action suffered significant rail damage.
In my discussions with other members over this the only feasible reason for this to happen with what we understood of the matter and mechanics of it was the extractor claw on the mauser styled bolt was very worn allowing the round to stay chambered, slipped over the rim of the round then stove piped the 2nd into the primer.
The rifle is a wall hanger now and thankfully the shooter is AOK also as our range is closed pending repairs to the stop butts (has been for 12 months and will be for another 4 months :mad:) our military shooting has ceased the next closest range lost all their electronic targets in the tragic Yarloop fires so that range is closed as well putting the next closest range 1 1/4 hours away driving at 110kph......so no shooting from this section here.
So it's a civvie term...that would make sense.Quote:

I had never heard it prior to reading the internet and recent gun magazines. Certainly not a common military term.Quote:

It never occurred to me that the terms might be unfamiliar to some folk! Parashooter's reply is very good, so not much need to elaborate further. Except to say I've been a fan of controlled round feed from an early age.
Whoever taught/told you that is apparently unaware that the Lee was explicitly designed to be single loaded-directly into the chamber with no breakage hazard. Those who doubt this should consider how the magazine cut-off functions in those models that have one and that the extractor design is the same in models without cut-off. The British service Lee extractor is purposely shaped and sprung to allow it to snap harmlessly over the rim of a chambered cartridge.Quote:

Even though the evidence of effective "controlled feed bolt actions" goes back to well over a century ago and the Lee action at the very least... the terminology and the public knowledge seems to have sprung up quite recently. I was certainly never instructed about it.....
I did a little googling and found one instance where the terminology and a few dodgy operating demonstrations proved that the winchester 70 rifle was far superior to the remington 700.
Perhaps it was an invention of a manufacturers advertising department.... Just like the whole headspace fiasco all over again.
Controlled Round Feed vs. Push Feed - YouTube
I'd never heard of this civvy term either. We always referred to it as a totally controlled feed mech or a feed mech with a 'twilight zone'
Parashooters thread also goes part way to explain why if you look carefully, you'll see a slightly rounded part to the underside of the extractor claw. That's to allow the rim of the rim of the round to slide under the claw as it is riding up the bolt face. Otherwise the extractor would be slicing off a sliver of brass each time it fed a round. Clever eh! Some people think that this slightly rounded part of the claw is wear. Not so.
Nothing like a light oiling and a pull through before the day starts to ease a lot of unecessary anquish!!
