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.

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".
