for the Snider shooters out there.

.577 Snider-Enfield Rifles and Carbines, British Service Longarms 1866-c.1880 by: Ian Skennerton

This is a great book to read for a complete historical look at the development of the Snider breech loading conversion rifles. Goes through all the design testing, various Mk's, testing results, basic proof stamps etc.

I have found it very interesting and helpful. This is the 2003 updated version.
