I recently acquired an H&R topper in 12ga / 3". I have been told by a friend that it is not wise to shoot 2-3/4" shells in a 3" chamber. He said if the chamber was ramped like a forcing cone it would be safe. However, if there was a ridge/ledge that the chamber was designed ONLY for 3" shells and mine has a ridge. I'm sure there is someone here who knows about this and can straighten me out. Thanks.
