Well I don't have the means whereof to fire my shotguns while suspended in space, in fact I don't believe this can be accomplished within the confines of gravity. While true this info is of little practical value to me. As I do fire my guns from the shoulder then the ppoint of contact at the butt is below the bore axis, which does indeed cause the end of the bbls to rise upon firing as they are pivoting off that contact point. The flip we are speaking of comes about by the muzzle not rising quite as fast (In proportion to its length) as the breech, or it "Bends" a bit.

This could all be seen clearly if one could simply shoulder a gun, mark the bore axis point on a target & then without moving fire the gun. You could then compare the center of the pattern with the where the bore was actually pointing. Marking directly above this center point by the amount of drop of the charge over that range would show where the bore was pointing at the tim the shot left the muzzle. "IF" you could then without changing anything else liminate the "Flip" & fired another shot you would get a point of impact slight above the first firing.

Remember that "Flip" does not necessarily mean the gun is going to shoot Below where its bore was pointing, it just won't hit as high as if it didn't exist.

Do I recall Brister describing the flip by the flexation of a cane pole...that if you held the stout end and attempted to quickly flip the far end upward, the middle of the pole would first rise while the far end would arch downward before rising? It is easy to see in a pole, but does a barrel do it to a much lesser extent?

Brister might have said that somewhere, but he didn't use that analogy in the referenced passage from his book.

It is always so distressin' to have these enlightening discussions remind me of how much I must have missed by dozing in my physics classes at Hogwarts.

So I'll be off now to work on an anti-flip spell for my bamboo barreled guns so as to optimize my fire hose shooting technique.

have a day

Don't trouble yourself too much-any day now, you kalifornicators will be down to assault butter knives, and the fragrence of spent gunpowder will be but a fond and passing memory....

Best,

But what does it matter? I'm dense, I guess, but what does it really matter if the barrel screws itself into a corkscrew, and then straightens itself out after firing? Isn't what matters, where the shot charge hits?

All we do is manipulate the drop, pitch, etc., to get the shot charge to hit where we want it to. Regardless of what configuration the barrels are in.

I'd think if some deflection or vibration happens to the barrel, wouldn't it matter how the shooter dampens or may affect that vibration.

edit to add, aren't some flinches the inability to do the require muscle input rather some additional recoil altering muscle contraction, so things like release triggers were developed.

Craig: from flip to flinch

"Flinch", "yips" in golfers, and a host of other movement disorders are now classified as a 'Task Specific Dystonia'
http://www.wemove.org/dys/dys_flimb.html

The problem has ended the careers of some professional golfers and musicians. Aynsley Smith PhD, Director of Sports Pyschology and Sports Medicine Research at the Mayo Clinic, Rochester, and Dr. Charles Adler of the Mayo Clinic, Scottsdale have researched the problem extensively, and a 'cure' remains elusive.
Mine is so bad that I 'flinch' trying to click the mouse

A different issue is the anticipatory lunge forward in response to recoil. I briefly, in the mistaken notion that it would be fun, tried a .410 chamber adapter in a 20g and found myself shooting a foot under the skeet targets at station 2 from lunging forward against no recoil. No idea what the barrel was doing.

Stan, "the matter" is that a sxs, if stocked to the same dimensions as an OU, may shoot lower due to flip. You're correct: what you do is "manipulate" the dimensions to change the POI. Brister suggests that an advantage of a sxs shooting lower is that it can be stocked higher, which allows the shooter to see more rib. In my own case, I've recently determined that on rising birds--woodcock being an excellent example--I seem to shoot better with a sxs with less drop than some I've used previously. 2" DAH or close to it, rather than 2 1/2".
