I need a book, or even better a website(s), that would give me a good picture of the state of the art in rifles made mainly for accuracy and range that commonly existed in the various world armies during those years. Anyone know of such or similar? I'm writing a Western where the protagonists are 4 deserters from the Mexican contingent of the French Foreign Legion who were themselves early versions of snipers. It is set in New Mexico in 1867. This is assuming the French Foreign Legion had any versions of snipers, formal or informal, at this time. If you know they didn't, let me know that too.
