Anti-material sniper rifle! Firing the Soviet era 14.5 mm. anti-tank machine gun round.

"Iran’s Shaher 14.5mm Sniper Rifle: A Killer At 2 Miles [3.2 kilometers] Away?" 

"It was almost a decade ago that Iran first unveiled its domestically-produced 14.5mm Shaher anti-material sniper rifle, but since its introduction, a lingering question has been whether it is actually up to the task. The Islamic Republic has faced an arms embargo for years, and it attempted to create its own domestic arms industry."

"The Shaher is not a lightweight weapon in any sense, and weighs in at a reported 22 kg (49 pounds), while it is an ungainly 1.85 meters (6.1 feet) long. Its anti-armor rounds can reportedly penetrate 50mm (two inches) of armor, and Iran also boasted that the rifle could be used to engage helicopters and other low-flying aircraft."

Surprisingly [?] so there is a slew of such big-bore [14.5 mm] anti-material sniper rifles on the market. See the listing thanks to the wiki. Anyone consider this to be odd?

Additionally with a comment from an acknowledged weapons expert:

"When your target is 2 miles [3.2 kilometers] away and important enough to drag a 50 pound [22kg.] gun from some undisclosed location, then take the time to set up with a very well trained specialist who has to compute wind direction, earth's rotation (true!), temperature, humidity, and exact range before taking a shot, maybe it is just time to call in an air strike."

I CONCUR 100 %.
