Thanks for posting.. I liked this post "7n6 was taken out of service in 1992. Now is civilian only. Next round was 7n10. In 1998 was adopted 7n22. Its penetrate 5-mm armor plate at a distance of 250 meters. 7n24 was adopted in the same year and penetrate 5-mm armor plate (steel '2P' - from this steel made BMP and BTR) at a distance of 500 meters. Newest cartridge - is 7n39 'Needler' its penetrate 24(!!!)-mm plate from normal steell at a distance of 100 meters and armor plate '2P' at a distance of 550 meters. Settings bullet and gunpowder look in google. 'The 5.45 is a good round but it is a little weaker, its just a fact.' Fact??"
