Other mistake: Interior Minister Roger Frey advises Commissioner Lebel that all members of the police, military and other security forces attending the ceremonies on the day the Jackal is expected to strike will be issued with lapel badges at the last moment, in case he is going to try to masquerade as one of them. We see hundreds of such people in the next part of the film, including Lebel himself and the CRS private who allows the heavily disguised Jackal through the barricades around the site of the ceremony DeGaulle is due to attend. Only the CRS private wears a lapel badge. Not one of the other police or military officers in attendance is wearing a lapel badge of any kind. (01:58:15)

The Day of the Jackal (1973)
Ending / spoiler
Directed by: Fred Zinnemann
Starring: Edward Fox, Michel Auclair, Terence Alexander, Alan Badel
De Gaulle moves forward at the last second, dodging Jackal's bullet. Lebel storms into the room and kills The Jackal. 'Calthrop' turns up at his flat, showing that he wasn't The Jackal.

Caron: You know, sir, what they'll do to you if you don't catch this man in time.
Lebel: I've been given a job to do, so we'll just have to do it.
Caron: But no crime has been committed yet, so where are we supposed to start looking for the criminal?
Lebel: We start by recognizing that, after De Gaulle, we are the two most powerful people in France.
Trivia: The Jackal demands $500,000 (US) to assassinate De Gaulle, which seems like a modest amount for such a dangerous job. However, when you take inflation into account that's the equivalent in 2024 money of over $5m. No wonder his putative employers are surprised.
Question: What is cordite? And does it really work?
Answer: Yes, cordite is classified a an explosive, but it's rarely used as such. It's a common propellant for artillery shells etc. Realistically, the Jackal would have used a plastic explosive such C4 or Semtex for a bomb. And the mercury fulminate tipped rounds are a fantasy, it's so unstable, it would explode before it had left the barrel.

Chosen answer: According to Wikipedia: "Cordite is a family of smokeless propellants made by combining two high explosives: nitrocellulose and nitroglycerin, i.e. it is a double-base propellant. However, Cordite N, a triple-base propellant is also used. Cordite is classified as an explosive, but it is normally used as a propellant for guns and rockets." So yes, it works.
