Pressure signs in different guns?
What is the cause for different pressure in same caliber guns but each their own? I am running 27.3 gr benchmark with a 35 gr berger bullet (204) and see no pressure signs and very accurate and fast. But some others have blown primers or other signs of excessive pressures that they nust back off the charge. Is it other guns metals and tolerances much better or closer to specs than others guns and say manufacturer? Just trying to figure out how a grain or two can affect one gun to another as for excessive pressure build up.. Thanks Dan.
