Secrets of the Houston Warehouse by Virgil King was very interesting read .
However when you boil it all down there is nothing really ground breaking in it.
It mainly deals with finding the true accuracy potential of a gun by removing the wind factor.
It does confirm the accuracy improvement of neck turning and tight neck and fitted neck chambers.
That was pretty much known back then but not as widely as now .
It did confirm that a fitted neck with no clearance at all would produce one hole groups in his gun .
Thats the little secret Virgil talks about but never actually says that.
He mentions that he finds this secret out at the end by using a small piece of fine emery paper but does not say anymore.
The secret was that he used the emery paper to polish the case necks in a lathe so they just squeezed into the gun with a bullet seated.
It is not a practical way to load ammunition and only an experiment to show that neck concentricity and bullet concentricity in the chamber is very important.
