With the adoption of the SVD a design team headed by Victor Sabelnikov was tasked with designing a new 7.62x54R load. This was to decrease the dispersion of the new rifle while at the same time increasing its leathality. The result of their work was the 7.62x54R 7N1 Sniper load. Externally the 7N1 looks identical to standard steel cased LPS ball ammunition. There is no color coding on the bullet tip or primer annulus, and no specialized head stamp to differentiate it. The headstamp simply consists of 188 (Novosibirsk Low Voltage Equipment Plant) and year of manufacture. For all intents and purposes it appears to be regular ball ammunition. Pulling a projectile one notes that the 7N1 is topped with a 152 grain FMJBT projectile. This is loaded on top of a charge of extruded powder in a Berdan primed steel case. In standard Russian practice the primer is corrosive.


Externally comparing a 7N1 projectile to a standard ball projectile one finds both projectiles feature a copper washed steel jacket, but there the similarities end. The 7N1 projectile is slightly longer and features a more pronounced boattail with a noticeable hollow base. Cutting the projectile in half quickly reveals the 7N1 to be a well thought out sniper load. Sectioning it reveals an air pocket in the nose (similar to Sabelnikov's later 5.45x39mm 7N6). Below the airpocket is a 37.5 grain mild steel cone shaped core of .269 diameter and .520 in length. This sits on top of a 72.6 grain lead 'knocker'. These are pressed into the jacket leaving a hollow base with a depth of .100. Overall projectile length is 1.275 and diameter is .311. During flight, due to the air space in the nose, the projectile's center of gravity is toward it's rear. However, upon impact the lead knocker pushes the steel core forward into the airpocket and changes the weight distribution of the projectile. Thus destabilized, the projectile will yaw instead of simply punching a .30 caliber hole in someone. While not new, the British did something similar with their .303 British MK VII ball load prior to the First World War, this design is effective. This is an obvious attempt to increase the wounding potential of this FMJ projectile.


To increase accuracy this load was manufactured to much tighter tolerances than standard ball ammunition. The Russians claimed an increase in accuracy of 2.5 times over standard ball ammunition when fired from an SVD Dragunov. My own testing has shown that to be a reasonable claim. Muzzle velocity from the SVD is 2,723 fps, with the trajectory closely matching that of standard LPS ball. To identify this load it must be in its original packaging as Factory 188 also produces ball ammunition. It comes packed 20 rounds to a paper packet, 22 packets to a metal tin, two tins per wooden case for a total of 880 rounds. The wooden shipping crates, hermetically sealed metal 'spam' cans, and individual paper packets are all distinctly marked "SNIPER" in Cyrillic. This is the load that was used throughout the war in Afghanistan and in Chechnya.

poddzwiękowy "mosiężny" kolor, na końcu łuski przy pocisku czerwony pasek, pocisk czarna końcówka stożka tak ok 3mm i poniżej pasek koloru ciemny granatowy lub szarozielony. Występowały i takie i takie. Kryza szarozielona. Na dnie łuski nr 711 i dodatkowy numer (data produkcji). Wszystkie były robione w Klimowsku, poza pierwszymi eksperymentalnym z Tuły. J
