Does a Darne, with the angled obturator discs, actually kick less?

MK,
I shoot a 10 gauge Darne R-16 that weighs about 7 lbs and find the recoil depends on the shot charge and powder behind it. Seriously doubt the obturator discs have any effect and suspect that you'd have to do a Sherman Bell "Finding out for Yourself" to be sure, but not sure I'd want to take my obturator off as part of the experiment!
Regards, Tim

What would be the theory that they would kick less?

Agree with R'man, I can see no reason for the obturator discs to afect recoil either way, more or less. Recoil is affected by Wt & velocity of "All' that is ejected from the muzzle vs wt of the gun.

The theory is that the discs which are slightly angled, support the base of the cartridge squarely and there is no room for the case to slam back against the standing breech, accentuating the recoil. This was put forwards by some of the Brit gun experts and, I think, in some Darne literature.

One more attempt to over come the laws of Physics. Recoil is a force and is limited to the rules of physic. For every action there is an equal and opposite action. You might convince some one that the felt recoil, which is subjective, may feel different. But anything that can be measured will be not effected. If this is not so every British gun made in the last 50-75 years would have tried to duplicate this feature is some fashion. Gun makers look for any "improvements" to stimulate the need for new sales and they never followed suit.

When a Darne is fitted up correctly, the cartridge rim is actually compressed between the sliding breech and the cut in the end of the barrels. In theory, it is not allowed to move at all, however, I have handled far more then one Darne in which the ammunition happily wiggled about when the action was closed on it.
My suspicion, is that Regis Darne designed the gun with a zero clearence fit for the sake of the action, and the wood of the stock, not for any reduction in recoil, and the action later proved to be durable enough to relax the tolerances a bit.
The ammunition clanked around in my 1970s vintage 20 gauge R15-it is held tight as a gnat's kiester in my 1946 R10.
No difference in performance, or, recoil, between other, similar guns that I could tell. BIg number rounds still kick harder.
Best,
Ted

http://books.google.com/books?id=nLq3yaV...&output=htmthe link should be to page 298 of Michael McInstosh "Best Guns", the last two paragraphs include his comments about the angled obturator discs and the low recoil. I note that he does not claim to have experienced this himself ....

This 'theory' has now attained 'Urban Legend' status!
R10 and R11's come without the discs and I have never read where an R15 has less recoil than an R10. I have owned a 12 gauge R10 and R15 and there was no difference in recoil between the two.
As corretly stated the 'Laws of Physics' do not allow for the discs to affect recoil.-Dick
