Somewhat related for those with older 12ga guns that might be 2.5" as opposed to the newer 2 3/4" i see that Fiocchi has introduced a line of ammo in that size. Not cheap though!

The length we see as a shotgun shell (ie, 2 3/4" or 3" or 3 1/2") is actually the length of the fired shell.
Newer plastic (or older paper) shells have the extra material from the roll or star crimp, which adds about 1/4" to the OAL of the fired shell compared to unfired.
Old all-brass shotgun shells didn't have this extra material, so their 2 1/2" long shell stays that length when fired. So yeah, a much older shotgun (damascus barrels too probably) will have a 2.5" chamber.
Think MagTech still does a run of all-brass shells in various gauges every now and then, but you are looking at $40-50 last I saw for a box of 25 empties. And they are set up to take either rifle or pistol primers, not 209 primers, so if you want/need to use those you'll need to mod each shell ...
