My experience has been that some break open guns (winchester 101 in particular) have tight chambers and require perfectly sized shells. I tried not resizing for a while and just could not put up with the poor fit of shells and the number that would not chamber correctly. Sometimes the shell would drop in the chamber but the gun would not close. I have gone back to resizing everything. Rim thickness and the flatness of the face of the hull can be very important factors in whether the shell chambers.
I use a MEC with the collet sizer and I don't see that sizing causes much if any extra work. You have to deprime anyway and it resizes at the same time, so what is the problem?
