While looking for images (no, I cannot read the text) in the pages of a shooting manual from Russia, dated 1884, I came across the image of a sectioned cartridge. In this situation taking into account artistic license, I assume it is a 10.67mm (10.67x58mmR? or 10.67x47mmR carbine? or ?) drill or dummy round. The aspect of this drawing that I find most interesting is the complexity of the cartridge. It appears to have a long rod extending from the primer pocket well into the cartridge case and long spring running from the inside base to the bottom of the oddly shaped bullet(?). The complexity of this cartridge sort of reminds me of a Hollifield Dotter cartridge http://cartridgecollectors.org/cartridge-of-the-month/30-06-Hollifield-Dotter or some later date drill cartridges that have an internal spring.
The title page from the manual and the cartridge drawing in question are shown below
