The Winchester Navy / Marine Corps Model of 1895 is a pretty cool design that was a bit ahead of US metallurgy at the time. It is a camming semi-straight pull action designed by James Paris Lee, of Lee Metford and later Lee Enfield fame.
Winchester actually had to increase the length of their testing rifle range for the 6mm Cartridge. They supposedly bought some property on Long Island so they could go out to 1,000 yards.
It saw service with the Navy and Marines during the Spanish American war of 1898, the Boxer Rebellion in China 1899 to 1901, the Phiilipine-American war of 1899 to 1902 and the Moro (Islamic) rebellion of 1899 to 1913.
The Navy and Marines also had machine guns chambered for the 6mm Lee Navy cartridge. They had some interesting requirements involving shooting through the sides of steam boilers used by river gun boats.
