I think that Gnomon has addressed rather well why 2.5 inch chambers in a SxS, particularly vintage SxSs do not negatively affect their value or their resale market.

And I do not disagree with him on the costs of 2.5 inch shells not being exorbitantly priced.

B&P's High Pheasant loads, which are a wonderful and deadly low pressure hunting load, sell for less than 12 bucks a box. Few premium 2.75 loads comparable in quality, can be had for under 15 bucks a box.
