2 1/2 Chamber 10 Gauge

[bruce a lyons]

Have a 1879 WW Greener 10 bore with 2 1/2 inch chambers. Would RST 2 5/8 shells be OK? Any 2 1/2 inch shells available?

Have you had the chambers professionally measured? Or are you relying on sales info?

Even if they are 2.5 inch chambers, the RST cartridges you mention should work fine... IF the barrel walls have been measured safe to shoot. By a professional.
