As Edi suggests, the marks will probably be a "pad" where the barrel touches the for end, deliberately left by the factory.
The action also used the "L" shaped recoil lug, which I usually replace with a machined lug bedded into the stock when I do em, this lug is permanently bonded to the stock, the action is also supported by pillars between bottom metal and base of action.
Im not sure of the logistics legalities of getting a rifle to me from NI, though I am probably coming across on a one day trip within the next month - should you want me to bed the rifle,,,you could research ?
