just a lot of variable to digest to see what is most accurate. barrel diameter, length, fluting, rifling and other factors. then we could throw in whether a stainless barrel is more accurate than a chrome moly barrel!
i have even read stories in the past where a rifle builder trying to get every little measure of accuracy from a barrel would have removed half an inch to an inch and effectively decreased group sizes by a decent margin.
i believe there is as much artwork as there is science in building an accurate rifle.
Very true, but that uncertainty is part of what makes it interesting!
Personally I hope it never becomes only cold hard numbers ....

[QUOTE=Mercator;1480392]Your hand does not flex the barrel like a tuning fork. It only shifts the stock relative to the barreled action (or you could say it vice versa)
I think I understand how barrel vibrations work. The idea with finding ammo that the rifle "likes" is to find ammo that has the bullet exit the barrel at a "node" or zero position of the barrel, not when it is pointing up or down or somewhere else. I can't picture how the barreled action can move relative to the stock when it is tightly anchored in two locations inches apart. It seems more likely that either the barrel is flexing or that a pivot point exists where the barrel is threaded into the receiver. Comments?

There is movement of the barrel relative to the stock. It is easy to see. I'm looking for a description of exactly what that movement is.
the fore end of the rifle is flexing, not the barrel. the barrel only moves a few thousands of an inch when fired. it can't be seen with the naked eye. it can be caught with very high speed cameras and viewed when slowed down.
the action and barrel are heat treated after rifling and machining. if the barrel could be flexed by hand, then do you think that barrel would be safe to shoot?

Just wanted to add, a free floated barrel by itself is not the cat's meow of rifle construction. It is often advertised as a big deal, but actually it is a way to sidestep the stock fitting procedures. A good bedding whenre the barrel and the stock oscillate in harmony is more expensive.
