Hello.
This is the first time I've seen information about the production of Dum-Dum bullets designed by engineer-lieutenant colonel V.A. Ivanov in the Soviet Union and their use in the Second World War.
Here is a photo and a link to the publication -

Does anyone have these cartridges in their collection?

assistant802,

Sir, a very interesting subject. No, I have none of these cartridges in my shell collection and did not know the Russians used such ammo. In the 1970s, my NH neighbor was a German WWII soldier who served on the Russian Front until his division was transferred to France in 1944. He told me his unit had to Turn In all their "special" ammo before they got on the train to go to France. He told me his unit used special ammo, which probably violated the Hague Convention Rules on military ammo.

Tell us more on the use and issue of this Russian Dum-Dum ammo, please?

Translation of text from photos -

The "explosive" (essentially expansive, containing no explosive) bullet designed by Engineer Lieutenant Colonel V.A. Ivanov was successfully tested at a firing range in 1939 and recommended for adoption. This type of DD bullet was designed to increase stopping power and inflict greater damage on unarmored personnel. The bullet's design is quite simple: a lead core, a bimetallic jacket with a truncated apex with notches, and a plastic ballistic tip. Plans were made to mass-produce these bullets at the Lugansk Cartridge Plant, but due to defective plastic tips, which were sensitive to moisture and shrinkage, mass production never took place, and Ivanov's bullets were never adopted. These bullets were revived during the war: in 1942, the Bishkek Machine-Tool Plant produced a pilot batch of simplified Ivanov bullets, without the plastic cap. The bullet's tip was exposed; according to regulations, it should have been painted white, but in reality, the cartridges were often produced unpainted. Cartridges with the DD bullet were produced for a short time; they are available with both brass and bimetallic casings. The Ivanov bullet weighs 11.4-11.6 grams, with a lead core weighing 9 grams.

 

The Dum Dum name comes from a municipality in India where the East India Company had a British-Indian arsenal that produced percussion caps and developed one of the first expanding bullet types.

 

That's right—in the Northwest Frontier action they found the early Lee Metford bullets weren't terribly effective "manstoppers," not as good as the .45 Martini and not even close to the hollow-nose .577" Snider bullet. Dum Dum is near Calcutta.

Legendary Finnish sharpshooter Simo Häyhä was reportedly hit in the face with an "explosive bullet."
Somewhat related: some 30 years ago I met a veteran French Foreign Legionnaire. His wife taught French at a local college where I was teaching German at the time. He related how he and his fellow legionnaires notched their bullets when combating the Viet Minh in at-the-time French Indochina. At that time the French forces in Indochina had the MAS 36 as well as the US M1/M2 carbine. I'm guessing they notched the carbine ammo to compensate for its lower hitting force.
