This is the steadiest of all positions, because it supports both the firearm and the hunter's upper body. The hunter's hips and legs provide a stable platform. This position is very comfortable and should be used to practice the fundamentals of good shooting.
This is the next-best position for steadiness. With legs crossed at the ankles, the hunter's knees gives support to the arms. But a hunter's legs will start to shake if this position is held for a lengthy period.
In this position, the hunter's arms are not supported, making it difficult to take an accurate shot. With this position, there is an exaggerated movement of the barrel. Some hunters will use a tree, large stone or a "shooting stick" as a prop to help ensure an accurate shot.
This is an adaptation of the standing position, in which the hunter uses a rest to steady the firearm. The hunter will experience less barrel movement - a key to accurate shot placement.
