I'm interested in hearing about some techniques and equipment that people use to shoot long range in cold environments. Anything from clothing choices to how you set up your shooting location (sit and ambush). By cold weather I mean 10 degrees F to below 0 with snow on the ground. It's a lot easier to stay warm when you are on the move in cold weather but sitting in a static ambush position for extended periods of time can be difficult to stay warm, especially with snow on top of frozen ground. This is even more difficult when you need to be steady enough for a long range 1000 plus yard shot.
