Better still, a plate machined integral to the receiver all from one block of steel, which has been done.

All depends on how much time,money and enthusiasm one has to creat something.

For anyone worried about barrel thread wear and the method of plates that attach to the stock, be aware that Bells early 1920s Rigby .275 bore T/d feature mauser, functions just fine.
as do similar early vintage t/d Rigby mausers that come up for sale/auction.

The H&H lockscrew in the side of the receiver ring approach, is somewhat agricultural compared to the 'tool free' forend lever-latch system on a Rigby.

Thanks guys. I'll have to admit you lost me a few times there as I am most certainly not a gunsmith. But, I think you have given me a direction to go. I will talk to my smith about a full thread, lever release (like the rigbys) system.

And a 400H&H barrel? Food for thought, food for thought...

H&H has been using a different take-down method for many, many years. It keeps the barrel and receiver intact. The action and barrel assembly are removed from the stock together as one unit. The newer system requires alteration of the rear action tang to allow it to hook under a lip and replacement of the front magazine screw with a large headed screw having a slot big enough for a large coin to turn.

To take down, the front magazine screw is unscrewed and the barrel rotated up and away from the stock. To replace, hook the tang under the lip above the grip, rotate the barrel into position, and screw in the front magazine screw. You can't get much simpler than that.

There is nothing original about this kind of take-down system. All Newton rifles and Mannlicher-Scoenauer take down rifles used the same method. Both were dismountable without the use of tools, but the Newton system is easier to operate and provides an adjustment to allow for stock shrinkage.

In the Newton system, the hinged floorplate when opened becomes a lever to rotate the stock nut, which is threaded to a bolt protruding from the recoil lug on the action. This bolt is threaded with two different thread pitches, so that tightening the bolt into the recoil lug also tightens the grip of the stock nut on the bolt. The bolt is secured to the recoil lug by a lateral set screw. To dismount the barreled action the shooter only has to open the floorplate (which is not fastened to the magazine follower spring), rotate the floorplate until the nut is disengaged from the bolt and then lift the barreled action out of the stock.

Since the follower spring is anchored fore and aft in slots in the wall of the magazine, this arrangement does not allow for the magazine to be unloaded from the bottom, which calls into question African Professional Hunter Charles Cottar's allegation that the Newton rifle was prone to opening the floorplate involuntarily under heavy recoil and spilling the cartridges in the magazine onto the ground at most inopportune moments.

Westley Richards and Co have posted a couple photos of a takedown 416 on Padram. Interesting method, square threads and a sidelever at right rear of forend, looks something like a removable sidelock plate lever. Plates forend and front of action, similar to the H&H above.
