I have 2 factory rifles , 40x and 52d they both have .043 head space .Tony Harper's information should be kept in mind by anyone who is thinking about altering headspace.
I have graduated headspace gauges and checked my rifles, including a V22S and several Anschutz single shot match rifles. None are below .043", with four of them closing on .044". These rifles shoot well with good ammo.
If shooters wish better accuracy performance it is to be found with better ammo not by altering headspace to something other than what TKH describes.
