Yeah, but they're 2 3/4", which I believe had been the standard chamber length in old American guns, like your Remington, but not so on old British guns.
My Westley Richards had its chambers lengthened to 2 3/4", probably to help it sell over here, but I still only use 2 1/2" loads out of deference to its 1890 British beginnings.
That would be true with British guns, but I was directing my answer to Jerry's original question which was.... "To what extent are so-called heavy loads likely to damage an older American classic SxS?"
