it is eksplozivno-zapaljivim zrnom means explosive-incendiary ball. 11/55 is headstamp for early produced ammunition in ammo factory in city Užice, later headstamp will be changed in PPU acronym for Prvi Partizan Užice.

Hi

Some other explosive bullets :

Japanese 7.7 mm Naval Ammunition (tetryl)


"...The explosive bullet is capable of blowing a 3-inch hole in a sheet of aircraft Duralumin...." (http://www.lonesentry.com).

************
Shooting with Japanese explosive bullets is VERY heedless deed. Please, don't do it ever again! These tetryl-filled projectiles hadn't any other safety elements but a thin cloth patch between lead core and tetryl filling (with lead azide or lead styphnate mixed to explosive charge or placed behind the "méplat" of a tip). Even the factory-fresh bullets could sometimes explode in the rifle or machine gun bore, and your ammo were 50+ years old stuff. These bullets were definitely not any kind of "spotter" or "observation" ammo, because trajectory of them was different from that of other bullets, especially "FMJ Ball" projectiles.

Tetryl is also about the least suitable explosive filling for spotting bullets: It generates no smoke or bright flame to assist spotting of the hits in daylight and darkness. Japanese explosive bullets were presumably designed for anti-aircraft shooting with machine guns (but with rifles too! There were actually made rifles with anti-aircraft "sight moustaches", projecting to both sides of the rear-sight). Use of explosive bullets is allowed for A-A shooting by the Laws of War, but prohibited against non-covered enemy soldiers (of regular armies, dressed in uniforms), according to Declaration of St. Petersburg in 1867 - 68. Use of explosive bullets was also allowed for fighting against irregular "guerrilla troops" in the islands of Pacific Ocean, because the guerrilla warriors were "uneducated savages". (Wording again from the Declaration of St. Petersburg).

The real "spotting/observation" bullets had a point shape and trajectory similar to normal "FMJ Heavy Ball" projectiles shot from machine guns. Spotting bullet is lighter than a standard projectile but considerably longer. Trajectories were matching up to 800 - 1000 meters .......

Russian 7.62mm ZaRa Bullet
From : http://guns.connect.fi/gow/QA15.html

The most famous rifle-caliber spotting bullets were German 7.9 mm B-bullet and 7.62 mm Soviet-Russian ZR (later abbreviation ZP) explosive/incendiary bullet, pet-name "ZARA" (derivation from words "Zazhigano-Razrivnaya" - later "Zazhiganiya Pulya" = "Incendiary Bullet"). It was designed in 1933. It has a very clever striker mechanism with a brass split "safety sleeve", covering a sharp point of the striker and keeping it away from bottom of the priming cap

2: Priming (& booster) charge(s)
3: Copper alloy priming capsule
4: Safety sleeve, brass
5: Striker, steel
6: Striker capsule, "bimetal"
7: Striker support plate, brass
8: Striker capsule cover, "bimetal"
9: Bullet's jacket, "bimetal"
10: Lead core/ sheath; extends to the charge (1).

..... Millions of ShKAS cartridges were shot towards Finns during our Winter War from the infantry firearms of Soviet-Russian attackers and their aircrafts. Presumably a million or more of them were loaded with ZR bullets. (Including those, shot against Finnish civilians during the bombings of our towns and cities!) ....

A story today in Afghanistan

This’ll blow your mind

A SOLDIER underwent a five-hour brain op to remove a high-explosive bullet — which could have blown his head off at any moment.


Army surgeons donned BODY ARMOUR after the Afghan man was rushed in following a bomb blast.
Non-essential staff were evacuated when a scan on what was thought to
be just shrapnel revealed it to be a 2½in incendiary round.


Bullet ... contained 2oz high explosives

The Taliban bullet, containing 2oz of high explosives. was powerful enough
to have killed the entire surgical team. But the brave US medics succeeded
in delicately extracting it during the marathon operation at Bagram air base, Afghanistan.

Bullet ... the 2½in round removed by docs

Their unnamed patient — a member of the Afghan National Army — suffered serious brain injury but was recovering last night.Relieved Sgt William Carter, a member of the surgical team, admitted: "It was a real concentrated effort on everyone's behalf to ensure that we were all safe — and the patient was safe as well."
Radiologist Lt Col Anthony Terreri, whose scan revealed the bullet, said: "Initially I thought it was a spent end of some sort of larger round. Then I saw that it was not solid metal on the inside."
The military hospital went into immediate lockdown and bomb disposal experts were called.
After the op the bullet was taken away to be destroyed.
It is the first time such daring surgery has been carried out since the war in Afghanistan began in 2001.

In half a century US medical teams have tackled fewer than 50 cases involving the removal of deadly explosives from patients.
Sgt Carter said: "This type of situation is remarkable."

I would say the line "could have blown his head off at any moment" is exaggerated by a journalist. As far as I know, these unfuzed incendiary rounds need a large impact to cause them to detonate. If it did not detonate when it initially impacted his head there is presumably nothing during the removal operation that could have caused it to detonate. Nonetheless, he was very lucky to survive.

"could have blown his head off at any moment" is exaggerated by a journalist. .

This is what makes him a journalist no?
