Standard +P pressure limits are established by SAAMI for certain cartridges; in general the +P pressure is approximately 10% higher than the standard pressure (see chart below). SAAMI does not have a +P+ pressure standard, but this indicates a pressure that is not SAAMI standard and may be higher than the +P loading.
The offset is added to the pressure reading to arrive at the peak pressure reading. Other benefits of the SAAMI conformal transducer are: very adaptive to the high volume quality control testing demands of commercial and law enforcement ammunition production; protection of the transducer from direct exposure to the high temperature combustion ...
Chart of SAAMI pressure levels for common cartridges, in PSI or CUP. A study Archived 2007-08-20 at the Wayback Machine done that shows a statistically significant correlation between CUP and PSI for rifle cartridges. Speer Reloading Manual Number 11, Omark Industries, 1987 [ISBN unspecified]
The CIP rulings indicate a maximum pressure of 230 MPa (33,000 psi). In CIP-regulated countries, every pistol/cartridge combination is required to be proofed at 130% of this maximum CIP pressure to certify for sale to consumers. [9] The SAAMI maximum pressure limit for the 10mm Auto is set at 37,500 psi (259 MPa). [10]
The SAAMI Maximum Average Pressure (MAP) for this cartridge is 441.3 MPa (64,000 psi) piezo pressure (54,000 CUP). [10] According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings the .300 Winchester Magnum can handle up to 430.00 MPa (62,366 psi) P max piezo pressure.
The 6.5mm Creedmoor (6.5×48mm), [6] designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. [4] is a centerfire rifle cartridge introduced by Hornady in 2007. [7]It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name.
This means that .45 ACP chambered arms in CIP-regulated countries are currently (2016) proof-tested at 170 MPa (25,000 psi) PE piezo pressure. [11] The SAAMI pressure limit for the .45 ACP is set at 21,000 psi (144.79 MPa) piezo pressure, [14] while the SAAMI pressure limit for the .45 ACP +P is set at 23,000 psi (158.58 MPa), piezo pressure.
Within firearms, chamber pressure is the pressure exerted by a cartridge case's outside walls on the inside of a firearm's chamber when the cartridge is fired. The SI unit for chamber pressure is the megapascal (MPa), while the American SAAMI uses the pound per square inch (psi, symbol lbf/in 2) and the European CIP uses bar (1 bar is equal to 0.1 MPa).
