I have heard and read that there have been problems with 2" shells having the shot "ball" into almost a solid mass when shot in longer chambers. Theory is that escaping gases cause the problem because the wad can not create a gas seal in the chamber and the hot gases cause the shot to almost weld into a solid or semi solid mass. Never seen it or done it myself. Sold my 2" gun and still have a few boxes of reloads on hand. Best to ask a few of the members here from Great Britain if this is truth or just another urban legend.
An 'Urban Legend' from the early 20th century shells that still persists to this day. I have a 2" Tolley and have used 2" Gamebore shells out of a 12 gauge Darne for many years with no problems. I will sit and shoot 2" modern Gamebore shells all day out of any 12 I own if someone pays for the shells.-Dick
