You won't find any degraded patterns.
I'm not sure why Lightfield says 2.75" slugs out of a 3.5" chamber is bad.
Maybe it has to do with the longer jump to the forcing cone. In rifles a longer throat (distance to grooves) usually isn't good for accuracy.
With shot this doesn't matter, because the design is already somewhat erratic to begin with; you are just forcing a pile of bb's with a cup. Small cup imperfection isn't key here as there really is no accuracy anyways, only group size, which the choke takes care of.

Thanks for the replies and guidance, I searched around on the Internet a little more and found this on the browning website. It seems to suggest that bigger the difference between the shell size and chamber size the worse the patterns will be. The charts indicates that a 2.75" shell shooting out of a 3" chamber will have an inferior pattern then out of a 2.75" chamber. If this trend continues then the pattern out of a 3.5" chamber will be dramatically poorer or does it level out at some point? Is this true? And what could be the reason? Should I even care? Now I am even more confused then before . here is the link
i shoot skeet with 3" chambers and 2 3/4" rounds, as to a lot of people and i don't see any impact, nor have i known any one to suggest it. From a patterning perspect shooting shot there is no difference that I can detect.
shooting a slug might be different and you'd have to experiment to figure it out. though the differences in the 2 different guns it would take to do this experiment would probably be enought to have some impact as well. So its going to be a really hard question to prove out.
In case you didn't search long and hard, see this back-n-forth where I explained the saga of long chambers vs. shorter shells.
Then you will have some greater perspective about logic (or lack thereof) and can make more informed decisions.
I can see why 2.75" shell will not be the optimal performer out of the 3.5" chamber. I just want a shotgun for small game, so I think I will stick to 2.75" shells but who still make 2.75" chamber barrels. It looks like all the factory made guns come with 3" chamber barrels? Any suggestions out there? looking for a pump, thanks
