The earliest .577 rounds were those loaded in 1866 and adopted as the 2" Snider cartridge.

Various sporting loads were developed in numerous case lengths up to 3 1/4".

The .577 2 3/4" round was in use for a number of years. Cartridges can be found from the early coiled cases to drawn brass with black powder loads to nitro-for-black powder loads.

This particular round is an early nitro-for-black powder loading. Later rounds has an "LC" in the headstamp and a projectile with a gas check.

A nitro load is also known, but these rounds used a full patched bullet.

This projectile is a standard paper patched 520 grain Express type with copper tube.

The powder is probably a Schultze type of nitro. The cotton wad was required to fill the void that would otherwise be created with the switch from a black to nitro powder. Schultze powder was one of the first smokeless powders made from treated sawdust and typically had the appearance of rough irregular granules.

This cartridge was headstamped: KYNOCH .577
