"The Sight of Such a Weapon Can Make You Crazy"

Yeah, just knowing it can shoot down airplanes...[More]

Why it can totally screw up one's sense of proportion.

Along those lines, JFC copied me on his correspondence to the "Authorized Journalist":

Dear Ms. Barry:

On 12.7-caliber miscalculation:

In "South Ossetia Tries to Disarm Its Citizens"

You wrote: "...12.7-caliber machine gun..."

Try .50 caliber Browning Machine Gun [BMG] (12.7x99mm NATO)

See:

.50 BMG
From Wikipedia, the free encyclopedia
The .50 Browning Machine Gun (12.7x99mm NATO) or .50 BMG

http://en.wikipedia.org/wiki/.50_BMG

For more conversions:

Inches mm
.177 4.50
.22 5.59
.357 9.08
.40 10.16
.45 11.43
.50 12.7

Cheers,

JFC
