Actually it is a Discovery Channel piece that I was pointed to by the anti gun bigot at "Freedom State Alliance". This time I actually mostly agree with him when he says:

This shocking video might be the best demonstration of the lethality and power of the .50-caliber sniper rifle – YOU SIMPLY MUST WATCH IT.

Drop the words "shocking" and "YOU SIMPLY MUST" and we've come to agreement.

There is some false/misleading information in the video however. Bolt action rifles don't take 15 to 20 seconds to cycle. And the AK round is seldom referred to as "308".
