Shooting Bag
Also: Support Bag · Game Changer
A filled fabric bag used to build a steady rifle support on a barricade, prop, or uneven surface in field and match shooting.
A shooting bag is a fill-filled fabric pouch that conforms to whatever surface you press it against, turning a hard edge into a stable cradle for the rifle. Filled with a light synthetic media, it can be squeezed and shaped under the forend or buttstock to take out wobble. On a barricade it becomes the contact point that lets the rifle settle instead of skating across the prop.
The bag works on the same loading principle as a bipod: you push the rifle into it so the recoil tracks straight, much as loading the bipod preloads the legs. A small firm bag steadies the forend where a bipod cannot reach, while a softer rear bag under the buttstock fine-tunes elevation. Popular squeeze bags picked up the nickname game changer for exactly this versatility across positional stages.
