In looking at the barrels they should be checked for chamber length (more than likely 2 1/2), condition of the bore (rust and pitting), thickness of the barrels.
Should the barrels check out ok, you should be able to fire ammo suited to vintage guns (POLYWAD, RST).
It is possible to reload 2 1/2 yourself in low pressure loads (sub 6000 PSI) using SR7625 and a roll crimper. For vintage gun we tend to shoot less ammo so the work of roll crimping does not seem to be a bother and is easier than buying a reloader just for 2 1/2
