It appears to possibly be a wood bullet 8mm Lebel cartridge, although OPs dimensions are off a bit. Possibly loaded at Frankford Arsenal, Philadelphia. I have no idea if any ammunition for the French was loaded by Frankford Arsenal prior to WWI, but the only FA headstamp code I find in international headstamp listings is Frankford Arsenal. Other than this I have no idea except is is probably European. Possibly the Ammunition Collectors Assn. can shed more light on this.
It definitely is not any American cartridge except manufacturer.
