The .600/577 Rewa, also known as the .600/577 Rewa Nitro Express, Holland's .600/577 and the .577 Rewa, is an obsolete big bore rifle cartridge.

The .600/577 Rewa was developed and introduced by Holland & Holland in 1929 by a special order for Martand Singh, Maharaja of Rewa.

The .600/577 Rewa is a rimmed, bottlenecked centerfire rifle cartridge. The .600/577 Rewa is derived from the .600 Nitro Express necked down to accept the .582 in calibre bullet of the .577 Nitro Express. The .600/577 Rewa fires a 750 gr bullet driven by 110 gr of cordite.

Always rare, the .600/577 Rewa was produced by Holland & Holland until 1957, although it can still be purchased from Kynoch.
