A buddy of mine had a box of .22 LR bullets when I was visiting him in Georgia. We went out and was doing some plinking the one day. Each time he shot, I only heard a "whisper" of noise. Almost as if the gun was silenced, but it wasn't. He said that they were a very "low noise ammo" and worked great for controlling pesky critters without disturbing the entire neighborhood. For the life of me I can not remember the brand of these and he is now in the military fight for us. Has anyone very heard of such ammo? If so, could you please direct me to a supplier as I would like to purchase some. Thanks in advance.
