Today at the place where I shoot trap, someone gave me a very old DM 6.5 x 54 Mannlicher case they found when clearing out their shed. The case length is actually a bit short, as 63.5mm. The headstamp is:
I know the maker, DM was the foreunner of DWM, but the FYA (Which I know is the abbreviation for “For rifles and machine guns” in Spanish) is a bit confusing. The Spanish site municion.org also says that this carridge was designed in 1899, but the date on mine is definitely 1896.
Was this a contract load for a Spanish-speaking country, if so, which one? And which country was using a 6.5 x 54 Machine gun (I didn’t know there was such thing) in 1896? This case also had some kind of fired round-nosed steel jacketed 6.5mm bullet pushed into the mouth to make an inert round when I got it, is this a correct bullet for this calibre at this time? This bullet is easily removable, and can be taken in and out by hand.
Last year, the same person also gave me a 7x57 Mauser with the same DM 1896 headstamp, same style of fired steel-jacketed bullet, and from the same shed.
