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 ...
The specification included a Remington-designed bullet and the use of IMR4475 powder, which resulted in a muzzle velocity of 3,250 ft/s and a chamber pressure of 52,000 psi. [8] In the spring of 1962, Remington submitted the specifications of the .223 Remington to the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI).
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Also, during this time SAAMI started the transition from using a copper crusher chamber pressure measurement system for ammunition to piezoelectric transducer chamber pressure measurement systems. [1] [6] In the 1980s, SAAMI conducted extensive testing of the reaction of sporting ammunition in various transportation accident scenarios.
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 .277 Fury or 6.8×51mm Common Cartridge [4] [5] (designated as the .277 SIG Fury by SAAMI) [1] is a centerfire rimless bottlenecked rifle cartridge announced by SIG Sauer in late 2019. [2] Its hybrid three-piece cartridge case has a steel case head and brass body connected by an aluminum locking washer to support the high chamber pressure ...
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.
SAAMI recommended Maximum Average Pressure is set at 65,000 psi (4,500 bar). Remington's ultra magnum cases were made wider than the .404 Jeffery case by .006 in (0.15 mm). The brass was made thicker so as to withstand the higher pressure of the new cartridge as the Jeffery cartridge had a maximum average pressure rating of 3,650 bar (52,900 psi).
