An Ohio-based gun company has developed the world’s first .905-caliber rifle that – at .905 – is the highest-caliber rifle in the world.

‘It’s a little scary,’ one user said of the gun in a Youtube video that demonstrates just how powerful the weapon can be.

The rifle is the creation of SSK Industries and is essentially a shoulder-mounted cannon, with rounds that look like mini mortar shells.

The rifle fires rounds about 2,100 feet per second with roughly 254,000 foot-pounds of muzzle energy. The gun also has 2,777 foot-pounds of recoil energy, which essentially makes it as powerful – and has about as much ‘kick’ – as firing 10 .30-6 rifles at the same time.
