I hate to be stubborn, but the original question was "what effect do 2-1/2 inch chambers have on the resale value of a gun?" It may be true that one can reload 2-1/2 inch shells. It may be true that 2-1/2 inch shells can be purchased, though not easily and not cheaply. It may be true that most of the people who post on this board think that 2-1/2 inch shells are great. That group encompasses maybe a few hundred shooters; add in all subscribers to upscale shooting magazines and the group is maybe a couple of thousand people (assuming that they all share this belief--unlikely). That would constitute a microscopic proportion of the shotgunning public and even a tiny proportion of potential customers for fine shotguns. So the potential market for a 2-1/2 inch chambered gun consists of those persons who reload or who don't mind paying an exorbitant price for shells when they find them and who post on these and similar boards. Unless the law of supply and demand has been repealed in this instance, I really think this must affect the value and marketability of 2-1/2 inch guns. By the way, I wonder if Purdey, H&H, etc. even make 2-1/2 inch guns any more; if they do, I bet it is a very small percentage of their total production.
