wikipedia vibration article - en.wikipedia.org/wiki/vibration
i watched the above youtube video the other night and had an epiphany - damping the forced vibration in a gun barrel shrinks groups. how the barrel vibrates, how much it vibrates, how much the barrel "whips" (a term i detest) all don't matter here. all that matters is damping the vibration.
there is another thread currently running that is discussing why and how browning's BOSS system works. there has been a lot of conjecture and anecdotal evidence put forth (and a good reference to a 100 year old scientific study) on this, but no explanation seems reasonable or logical. anyway, if you watch the video, and envision the microscope as being the barrel and the air conditioning unit being the firing of a shot in the barrel, you might understand how to damp barrel vibrations using a barrel damper, or by tuning your reloads.
i'm real interested in opinions as to whether my theory is crazy, or not. if not, i'd like your inputs as to why, or why not.
