If the ammo used is producing consistent velocities, you'll have to get out there quite a ways before you'll see the difference in accuracy that can be attributed to a light rifle versus a heavy rifle.
A rifle with a heavy barrel is generally more accurate than a lighter weight rifle. Heavy barrels take longer to heat up when shooting. Lighter rifles have thinner barrels that heat up much faster, thus affecting accuracy(even as close as 100 yards).
