You should be able to pull the wood away from the barrel with your fingers & see it snap back when released.
If there is no upward pressure by the stock to the barrel, add a metal shim, like a thin washer, under the tang and around the guard screw. This will have the effect of pushing the barrel into the forearm tip. Think of the front guard screw as the fulcrum or pivot. The shims under the tang allow the barreled receiver to pivot down, increasing forearm pressure. Remington made special shims just for this purpose. The were D shaped with a hole in the middle for the guard screw. The belly of the D fit under the tang. The shims were .030" thick. The shim had two points, like brads, one on each side, to bite into the wood to keep it in place. When stripping CMP 1903/A3 rifles, you'd occasionally find 1 and sometimes two of these shims (piggyback) under the tang.
