    Since all the shot goes down the same tube at the same time why do they spread around after they get out of the barrel? Seems like even with no choke they would travel pretty close together, what reason do they have to take off in different directions?

    Shot that is not perfectly round does not tend to go perfectly straight. Ron

    The turbulence each pellet creates as it travels down range also pushes them away from each other.

    Even perfectly round balls will curve and veer. Round isn't aerodynamically the cats meow with shot and air disturbances from each piece helps push another close by away. Hard shot deforms less and flies truer at shotgun velocities than softer shot. Even misshapen Hevi-Shot flies true with each pellet finding a weight forward balance in transit to target and that stuff is about the ugliest shot ever but patterns great!!!

    Because of the "Spreading effect"

    TB, that's a chain reaction from one ball hitting another via the cue ball. All the shot is traveling the same speed within reason and air resistance drives/peels them apart. That is the spreading effect with shot.

    "Since all the shot goes down the same tube at the same time why do they spread around after they get out of the barrel?"

    Do any of you actually believe that the first thirteen words of that quote are actually possible? What I mean is if a shotshell has a shot column 3/4-1" long there is no way it can travel down the tube at the same time. The first pellets in that column exit the barrel/tube before the last pellets exit.

    This fact alone could have some factor on the reason for the spread. I am not saying it is the whole reason but it does effect it some what. JMO

    I think the shot is held together by various forces. As it leaves the barrel it is released from those forces, allowing the mass of pellets to disperse. The further the shot goes, the further it is from the containing forces, the more it is exposed to outside influences, such as voodoo, the more the dispersion.

    I could be wrong though.
