What the hell does inspect the rifle more than discussed mean? Who would not look over a rifle before buying? The fact is the bolt closed on an impromptu field gage and he never would have mentioned it.
I have disproven the above comment about the headspace using a Forster Products .303 British FIELD Headpace gauge which the bolt does not close on. Please see supporting documentation if needed.
You posted your evidence in a thread and there were plenty of additional considerations given by other members including the fact that your field gauge is smaller than the British spec. My impromptu field gauge is a new A-zoom snap cap (made by Lyman) with a layer of tape on the head. It measures .006" larger than the snap cap which cycles, whereas your field gauge is only .004" larger. My No. 4 Mk 1* will not close on the gauge that closed in your rifle.
