The left arm is directly under the rifle.
The left elbow is leaned against the left hip or slightly to the right.
The rifle is placed on the fist of the left hand so that the wrist is straight and the hand is relaxed and the complete weight of the rifle is transferred to the bones - by the upper arm to the hip and further to the legs. Putting the elbow on the stomach or to the left brings instability of the position and unnecessary tension of the muscles in order to keep the rifle on the target. The wrist is straight and the left forearm has to be exactly under the rifle, that is, to follow the axis of the rifle. The balance of the rifle has to be on the rifle support and the hand. If it is in front of the hand, there is a slow, but unstoppable movement of the barrel since the COG of the rifle is forward. If it is behind the hand, the pressure is weaker on the hand and there is an uncontrollable jump of the barrel during triggering.
The shooter touches, holds and leans the rifle on the four points: butt plate, pistol grip, cheek-piece, and palm rest. The basic principle for the acquisition of the best conditions for a good shot is for the rifle and the shooter to make contact as best as possible. Under these conditions, the jump of the rifle during pulling the trigger is less and the effect of disturbance during triggering is minimal.
The butt plate is leaned against the right upper arm between the biceps and the shoulder. It should lean at least 5-10cm on the shoulder. This prevents turning of the rifle and its jump aside during triggering.
The right shoulder is relaxed.
The right arm is raised between 30 and 40 degrees, which allows better fitting of the butt plate on the shoulder.
