I'd say something else, but I think you pretty much just stuck a fork in that one Paul. That theoretical potato seems to be done.

Maybe you guys can compare barrel stiffness at different lengths and diameters?

Like: If a twenty inch .750"dia. barrel is stiff enough for a particular purpose, then how stiff by comparison is a .625" barrel that is only 12.5" long?

Dan Lilja has a bunch of math about that stuff here: http://www.riflebarrels.com/articles/bar...rifles.htm
It's way above my paygrade, I wouldn't stand a chance of figuring out something like that.
