There is a considerable difference in pressure generated by various cartridges of .308 bore diameter, and military rifles are built accordingly to handle the cartridges they were designed for; so you can expect variations in the heat treatments required. You say half finished bolt action rifle? Do you mean half finished action ? If so, has the action, bolt face, and lugs been squared ? This could affect your Rockwell readings based on the amount of material removed.
