Thanks for the many replies and Links. I am going to do a little smoking this weekend and see what touches where. I am also curious about the fit on a couple other SXS's I have that seem to be fitted well and see what/where things touch on those.
I will report back

Just read this thread, interesting. I was looking at one of my vintage British shotguns that had been rejoined back in the day, which is still tight on face but it does have a slight gap remaining between the barrel flats and the receiver flats. I had wondered about that. But according to Larry Potterfield and the late great Jack Rowe, there should be a slight gap remaining between the barrel flats and action flats when rejoining. I think it might have to do with accommodating for future wear in-order to maintain it staying tight on face? Maybe some of the gun experts can way in on the reason for the leaving a slight gap?

The barrel flats touching the action flats when the barrels are closed and locked is improper and if Jack Rowe was still alive he would tell you that the "trade" refers to this condition as "banging on the flats".
Our colleague on this BBS, Vic Vinters discussed this very issue in his book GUN CRAFT beginning on page 11 --the chapter titled "Jointing & the Circle. I am going to ask Dustin to post page 13 of this book which outlines how a proper fitting double gun should clear the action flats/barrel flats.
Also for those of you interested in the entire process of Joining a Purdey, you can review the other 4 episodes of the video that I posted above.
To believe that the barrel flats should touch the action flats is counter intuitive to physical science and gunmaking basic principles.

Loss of contact of the barrels with the breech face is a problem. In fact, there is a commonly used term for it... "off face", or as the British say, "off the face". And the rear of the barrel flats should not contact the water table. All of the informed sources I've read on this subject also agree with Stan, including "Shotgun Technicana". Here's a link to a pretty good article on the subject by gunsmith Delbert Whitman: https://shootingsportsman.com/re-jointing-a-gun/Thanks for the reference and link Keith. I missed your post this morning for some reason. Good stuff. ___________ Tim

If the gun is off face the breach end and lumps drop down the bolt does not move it comes off the bite so off face can give other. Symptom s this isn't a big deal other them explaining it ,put the gun on face then check the bolt.

![[Linked Image from i.goopics.net]](https://i.goopics.net/800/q31ibd.jpg) Salut, En rouge, les points auxquels le canon et les crochets, ainsi que le verrouillage, doivent porter d'une façon absolue. En vert, les canons ne doivent jamais toucher la bascule. 10 à 15 centièmes de garde au basculage est correct.

Great drawing,if the gap between barrels and action closes the lump goes down and allows for play in the bolt.the end
