Trying to figure out if the bullet jacket has any role in identification of the following Gras cartridges.
See pic below;
Top cartridge is an incendiary? (I believe–someone correct me if I am wrong). Headstamp is * SFM* (twined G’s at bottom), Copper primer with red sealant, tinned brass bullet jacket. Red sealant at case mouth.
Going down, #2 has a nickeled bullet and a brass primer with black sealant. Headstamp is GEVELOT *. Is this an M1883 ball?
Number 3 has a copper washed bullet, copper primer with no sealant (this is a maybe due to corrosion). Headstamp is * SFM* (twined G’s at bottom). Is this a ball round?
Number 4 (bottom) has a brass bullet and brass primer, no sealant. Headstamp is LM 4 36 LM. Is this a ball round?
If all are ball rounds why all the different bullet jackets?
Also, heard there is a new book on 8mm Lebel book by Huon that just came out. Anyone know how to get a copy here in the US?
Thanks in advance!
