I am in the process of stocking a Wesson single shot action and need info regarding the diameter of the through holes for the tang screws. Should they fit tightly the diameter of the screw or does there need to be clearence between the wood and the screw? There are two screws tying the upper and lower tangs together- fore and aft. There is an additional screw that secures the lockplate and am making the assumption that this hole needs a little clearence- is that correct? Thanks.
