Call of Pripyat in-game description

5.56x45mm SS109 is a NATO semi-armor-piercing rifle ammunition featured in the S.T.A.L.K.E.R. series.

Usage[edit | edit source]

This kind of ammo is used by the TRs 301, IL 86, SGI 5k, GP37 and the FT-200M. In S.T.A.L.K.E.R.: Call of Pripyat, the player can modify the AKM-74/2 to fire this caliber instead.

Appearance[edit | edit source]

Shadow of Chernobyl[edit | edit source]

In Shadow of Chernobyl this type of ammo can be found and bought by the player, in similar ways to other ammo, after visiting the bar. While it is very rare in the Dark Valley it will sort of replace the old 5.45x39mm ammo in regions further north, making a change to a compatible weapon beneficial, but only after completing all missions in the area. It is not found or sold further south.

They are easily found in the Wild Territory as 5.56 rifles are the standard weapons for Mercenaries and the Bandits in the area.

Clear Sky[edit | edit source]

SS109 cartridges are mostly non-existent early in the game and only become more common after the player exits the Cordon, where it is sold by most traders. It can be easily salvaged from fallen Freedom members.

Call of Pripyat[edit | edit source]

Unlike previous games, SS109 cartriges are common found in all areas, but is slightly hard to actually obtain without resorting to killing every stalker holding a 5.56x45mm firearm, or finding stashes. They are a bit harder to find than the more commonplace 5.45mm rounds, but still more abundant than most other munitions.

Owl sells them by default, however, unless one has done enough quests around Zaton that he'll lower his prices, he will sell a single box of SS109s at around +2000RU, which is very expensive at the start of the game.

Hawaiian also sells this type of ammo, however much like Owl's rates, unless one is friendly with Freedom or has done enough quests around Yanov, Hawaiian will sell them at very high prices.

Some boxes can be found in various stashes, such as beneath a house in the Izumrudnoye area of Zaton, and beneath a container in the Yanov northern tunnel, both found with a TRs 301.

General characteristics[edit | edit source]

Inventory icon

SS109 rounds have similar performance to 5.45x39mm FMJ lead rounds, but differ in that they have a hardened steel penetrator tip. The penetrator can pierce light cover or body armor and the composite alloy slug behind it will go on through. This gives them better penetration against heavier armor, giving the player a slight edge in the late game where heavily armored stalkers are a more frequent opponent.

It is also available in 5.56x45mm AP.

Trivia[edit | edit source]

  • The flavor text correctly describes the standard NATO service round as the SS109. However, the ammo carton has SS190 written on it and the game code calls it the ammo_5.56x45_ss190. The SS190 is the 5.7x28mm FN Ball round.
  • The ammo carton has the notation "525 Grn. M.C. Solid Bullets" on the lower right corner.
    • This line of text is found on the military-style ammo cartons.
    • Grn indicates the weight of the bullet in grains. The NATO-standard SS109 cartridge's bullet weighs 62 grains [4.0 grams].
    • M.C. indicates that the bullet is "metallic cased", a Remington Arms term for "Full Metal Jacketed" (FMJ). The SS109's bullet is covered in a copper sheath.
    • Solid Bullets indicates that the cartridges are Ball (lead slug) ammunition and do not contain a Semi-Armor-Piercing steel penetrator or Armor-Piercing metal core. However, the SS109 has a two-part bullet with a steel core in front of a lead (M855), tungsten-composite (M855A1 Lead Free), or copper alloy (M855A1 Enhanced Performance Round) slug.
  • The ammo carton says in the lower right corner that it holds 60 rounds. Military rifle cartridges either come packed in cartons that hold 20 loose rounds or cardboard spacers that hold two or three 10-round stripper clips.
