Ok, here is a really dumb question. I been told that the 2.75" slug have problems and act a bit erratic when shot out of a 3.5" chamber (according to Lightfield), but what about shells? Am I giving up anything when I shoot 2.75" shells out of a 3.5" chamber compared to a 3" chamber? Especially in term of pattern? My guess is no, but I am a newbie at shotgun so please help .
