I hate to be disagreeable, but...I think that 2-1/2 inch shells are pretty tough to find. Nobody uses them shooting at any type of clays (probably the only place of growth in shooting sports). If holding value (forget increasing value) is important, these obsolete and hard to get guns have to be losers, just as rifles shooting weird, hard to get continental bullets are losers. It is similar to guns with 26 inch or shorter barrels; they used to be the norm; they aren't any longer and they pay for it in the market. They work fine and if you like them, fine; just don't expect that they will be a decent investment or will be easy to unload, as I believe the 2-1/2 shells will be a (big) negative.
