[QUOTE="cajun, post: 2079100, member: 9772"] Actually it has been tested. Look up optimum barrel time. Or obt. There was a pretty healthy debate on some of the target forums at the time. The hypothesis was that by changing coal or powder charge you were basically changing the timing of the bullet exiting the muzzle. With each barrel there is an optimum point in vibration for the bullet to exit that creates the same poi. Guys were even taking a known good load and calculating the barrel time in ms and trying to duplicate the barrel time with another powder etc. fascinating stuff. If you’ve ever seen high speed video of a barrel as it is shot it will blow your mind how much vibration there is. [/QUOTE]
