The video explains a specialized technique called the "artillery hold" for accurately firing spring air rifles, which differ significantly from recoil-less PCP rifles or firearms. Unlike traditional shooting stances where the rifle is held tightly, the artillery hold emphasizes a loose, gentle grip on the rifle's stock and a light rest of the butt against the shoulder. This counter-intuitive method allows the rifle to recoil naturally when the internal spring fires forward, preventing erratic barrel movement and improving shot grouping. The video demonstrates this technique in various positions, highlighting how a tight grip causes pellets to scatter and how the artillery hold promotes a more fluid and accurate shooting experience by allowing the rifle to move as it's designed to.
