5.45x39mm 7N22 BP is a type of rifle ammunition featured in the S.T.A.L.K.E.R. series.
BP rounds have an armor-piercing metal core. This gives it significantly better performance over standard 5.45x39mm FMJ rounds against armor. Due to its higher penetration, it can even penetrate some thicker walls and floors with little difficulty.
The 5.45x39 is used by the AKM-74/2, AKM-74/2U and the AC-96/2. As well, the "Tunder" 5.45 is able to fire these rounds. In S.T.A.L.K.E.R.: Clear Sky, the player can modify the Tunder S14 and the SGI-5k to fire 5.45 rounds, and in S.T.A.L.K.E.R.: Call of Pripyat, the same upgrade can be applied to the IL 86.
Shadow of ChernobylEdit
These bullets can be found in several stashes - a large amount in a secret stash in Agroprom. Sidorovich may reward the player with these bullets after doing enough jobs for him. Monolith fighters using the Obokan make very common use of this ammunition, making it very easy to stack a large amount of these rounds by the end of the game.
These bullets are much more common in Clear Sky, being sold by several Loners traders, Mitay, and Professor Sakharov. They are used by Loners, Duty soldiers, and Military soldiers. Non-secret stashes in the Cordon contain these rounds, including one under the wrecked bridge, one in the Rookie Village, one in the Loners base, and one in the Military outpost. Similar stashes contain these bullets in the Agroprom.
Call of PripyatEdit
These rounds are quite common compared to prior games. Nearly any Stalker above the rank of Novice has a chance of carrying at least a few rounds, and most Veterans and Masters will carry them only. It can be easily salvaged from fallen Duty and Monolith members. Stalkers also use these rounds more often, making them more dangerous in combat compared to Novices and other weaker ranks. Both Owl and Hawaiian sell them regardless of the player's choices.
- The letters BP stand for Broneboi'naya Pulya, or "Armor-Piercing Bullet". GRAU Index: 7N22.
