How big an issue or important is it for a safely functioning rifle to have a matching # bolt? Seems since they have replaceable size bolt heads they anticipated there would be headspace issues and the bolt head corrects it. Would it being a rimmed cartridge be some sort of factor re head space? Could handloading for the specific rifle make a difference? In looking at Brit. websites on shooting surplus Enfields they don't seem to think headspace is that much of an issue.
