"Regarding, my ridicule for comparing a shotgun barrel to a violin, and why it has escaped all the great industialists, I will point to the existing science of cryogenic steel alignment which is offered to improve the patterns of competition shotguns and accuracy of long range rifles. It is based on principles of vibration, i.e. harmonics.
Regarding my riducule for stating that a long slow barrel taper increased pattern effectiveness, one must go no further than the makers of MODERN screw-in chokes to read their statements on shot deformation, and regulating choke to bore diameter."
I can only refer you to my first post. I have never seen ANY substantiated data to support ANY barrel mods or chokes that purport improvement. Any and all just ooze snake oil by the gallon.
Again - if any of that crap actually worked to do anything but lighten wallets then the factories would be on it like stink on shit. Right now we're looking at over a hundred year's worth of tinkering and the bbls still look pretty much like what Greener cobbled together in the late 19th Century. I wonder why? Well, actually I don't.
It's a shotgun.
Get over it.
have a day
