my fps difference in the barrels could be wrong, again, to illustrate a point. Several people here have already noted about patterns not changing from just barrel lenth. A 400 fps difference in the example (pretty much just pulled that number out of my butt) only made a difference of inches at 20yrds. Make it 100fps difference, and you will see very little difference with the pattern.
What I'm going here for guys is that barrel length can affect the pattern very slightly (took a 400fps drop to really see the difference), but not enough to worry about when choosing a shotgun for different purposes. Something a lot of the posters on this thread seem to already know so far.
Longer barrels do nothing magical to "stabilize" the shot cup. I would venture to say that the shot cup is pretty much done with all of it's changes due to acceleration within the first 4 inches of travel, unless you are talking about a tapered barrel.
