Choked mod/full, all original.
I’ll never try to make a 3” magnum out of it. Like me, she’s of an age that requires tenderness so I’ll treat her as such.I shoot RST 2 1/2 inch shells or load the equivalent in all my vintage SXS's. The gun can withstand modern shells with 1 1/8 oz of shot at 1200 +/- FPS but remember the wood is crowding 90 years old.
