I was discussing this phenomenon elsewhere with a fellow sxs shooter. The only reference I could find to it was in McIntosh's "Shotguns and Shooting" (p. 104). Nothing I could find in Brister, Zutz, nor in 3 books by Gough Thomas. MM says it causes a sxs to shoot somewhat low. Comments from the group on how big an issue it is for sxs shooters??

Are you thinking that possibly that sxs have more muzzle jump than o/u's?

I think I remember Churchill(?) claiming, as a means of promoting his 25" guns, that the shorter barrels had a tendency to flip upwards, compared to what he claimed was the normal tendency of 30" barrels to flip the other direction and shoot low. His, therefore, were better suited to incoming driven birds.

I believe that all barrels, even singles, exhibit muzzle "flip"
Muzzle "flip" is more of a problem for those of us who shoot SxS rifles and has to be really taken into account there. The right and left barrels do not flip the same.
A lot has been written about flip and you can find it on double-rifle sites. SxS shotguns have the same phenomenon but it is more easily demonstrated when you have a single bullet coming out of a barrel as opposed to a shot pattern.

Burrard talked about muzzle flip. Basically his consensus was the gun could be stocked to accomadate the flp for whatever length bll was desired. It would however be a mistake to have a 2nd set of bbls fitted of a different length as the fit could not accomadate both lengths. Been awhile since I read on this but as I recall he said the longer bbl would have greater down flip, don't recall any having up flip.

It would be interesting to see highspeed photographs of a SxS and O/U firing.
Mine's a tale that can't be told, my freedom I hold dear.

I've had time to look it up and here's a link to a very brief explanation of barrel flip in a double rifle: http://forums.accuratereloading.com/eve/...6481#2781096481Same thing for a shotgun. That's why rifle barrels need to be regulated for a specific weight bullet/powder. Bespoke shotguns used to be (I'm not sure if they still are) regulated for the new owner's favorite load.

Might be interesting to ask fitters who use adjustable try stocks what they find when setting up SxS guns. A stock head for each make of gun might not be available, so info might be limited to guns that can be attached to the try stock.
I recall an article by Chris Batha about small gauge SxS guns needing high combs to deal with barrel flip. I cannot recall why barrel flip is exaggerated in small gauge (28-gauge, for example). The barrels are thin and light, but recoil is low, seems the effects might offset, but apparently not in his experience.
