A little-known variant of the famous Dragunov SVD marksman rifle.

From the 1990s onwards there was a trend for NATO militaries to replace their 7.62x51 NATO sniper rifles with ones chambered in larger calibers like .300 Win Magnum and .338 Lapua Magnum, which delivered superior range and penetration.

Russia was a late convert to this trend, but in the early 2000s they experimented with creating their own high-powered sniper cartridge. They used the 9.3x64 Brenneke, a popular hunting caliber in Europe, as the base and created a new semi-armour piercing sniper round called the 9SN, with a 256gr FMJBT bullet having a heat-treated steel tip.

Although effective range was similar to that of the 7.62x54R round previously used by the Russian snipers and marksmen, it had the ability to penetrate soft body armour and light environmental barriers up to 600m.

In the end the new cartridge and rifle weren't adopted, presumably because compared to, say, .300 Win Mag, it didn't provide enough of a performance improvement over the standard 7.62mm.
