Why mess around with oiled cases at all? There is too much probablity of differences in achieved pressure, and as stated, that method does nothing to proof test the barrels. I would recommend picking the highest pressure load for your particular caliber and then simply use a 30% heavier bullet with the same powder charge. This method is KNOWN to increase the pressue by the same amount as the increase in bullet weight above the normal weight. It is predictable and repeatable, and it is a good test of the whole system of the gun. There are too many variables in oiled cases and it is an incomplete proof test as well. Bob H.
