With all this fuss about the .50 and LR shooting, I had to place my .02 worth! I'm on exchange with Charlie Coy, 3rd Bn of the 17th Inf Reg't, 7th ID out of Fort Ord, Calif. We are shooting aircraft drones with the M60A1 machine guns and we had a chance to wring out the .50 cal at gophers about 100meters away. Heeeere kitty kitty kitty ! 
And yes, the US Army Sergeants ordered ALL of us to UNDO our chinstraps because this is the post Vietnam US (read: all volunteer) ARMY. Their logic was that blast concussions would damage your spine/neck region during the upwards energy flow.
The best fun was the look on our Sr NCO's and Warrants when their orders to "Do up your chinstrap, you gas plug." Only to be disappointed when the US Top Sgt reminded them that we are in the USA and all chinstraps were to be left undone. Ah yes... the joys of a peacetime army!!
Yuk yuk yuk
Cheers,
Barney
