Metallic Cartridge Chamber Pressure Measurement

No method of measuring chamber pressure is accurate. If you measure 100 rounds of exactly the same load, in exactly the same gun, with exactly the same test equipment using the crusher method the measurements will typically vary plus or minus 5% from round to round. Some rounds may be off from the average for that group by 10% or more.
