The purpose of this is to provide a quick glance of cartridge specs for the curious mind. This means that the true average pressure of a load tested with one five-shot string will be different than the measured average. SAAMI Shotgun Pressure Specifications Shotshell Maximum Average Pressure (MAP) in PSI. PICTURES OF SHOT GROUPS: SAAMI CHAMBER: SPCII CHAMBER: The SAAMI pressure limit for the 9×19mm Parabellum is set at 241.32 MPa (35,001 psi) piezo pressure.

See summaries of new items by subscribing to the newsletter. Conversely, a load that has erratic pressure performance over a small sample size may not be representative of the entire set of potential rounds made to that prescription. The SAAMI cartridge and chamber drawings and velocity and pressure are available here. It is not intended to provide legal definitions of the terms included, and, in light of further experience, the definitions of these terms may change. This means that, should a particular 5- or 10-shot string exhibit very uniform performance, the large-scale average may not be as uniform. The purpose of this is to provide a quick glance of cartridge specs for the curious mind. Both were one-shot kills. SAAMI was founded in 1926 at the request of the federal government and tasked with creating and publishing industry standards for safety, interchangeability, reliability and quality, coordinating technical data and promoting safe and responsible firearms use. In the table below, SAAMI lists the MAP as 520 (x100 psi), or 52,000 psi. It accounted for a nice mule deer and a superb bull elk. The strengthened case allows the 9×23mm Winchester to operate under a higher internal pressure, 55,000 psi (measured with a piezoelectric transducer), in comparison to the maximum pressure of 36,500 psi for the .38 Super (current SAAMI standards). The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI®) has accepted two new Hornady-marketed cartridges, the 6.5 Precision Rifle Cartridge (6.5 PRC) and the 300 PRC. The author deeply appreciates contributions by 65Grendel.com participant rickOshay and Ammoguide member tloc54 that helped make this paper more effective than it might otherwise have been. Everything in that above paragraph that is stated about 45 Colt ammunition, could also be said of modern 45-70, 38-55, etc. For example, the bell curve in Fig 2 is representative of a five shot string producing an average of 50,500 psi. Who cares is equal pressure loads deliver similar velocities. Top . Statistical behavior guarantees that the true average pressure in their test hardware is different than the measured average. Does anybody know what the SAAMI max pressure spec is for the new 1886 Winchesters? Saami. 13,500 . It is all too easy to shoot a five or ten shot string, compute an average from the readings and call that one’s pressure. Our rights are under attack! Section 1 — Characteristics. ga('send', 'pageview');

The SAAMI Maximum Average Pressure (MAP) is listed in both the Copper Units of Pressure (CUP) and the Pounds per Square Inch (PSI). The MAP value was established by SAAMI to be the maximum average pressure for commercial load development. Firearm Safety Rules. . SAAMI specs give it a maximum average pressure of 65,000 psi, with a 140-grain bullet traveling at a velocity of 3,075 fps. The main difference between these two terms is that the standard deviation is not as dependent upon sample size. In the table below, SAAMI lists the MAP as 520 (x100 psi), or 52,000 psi. The curve represents the probability density for the standard error for five shots and the SAAMI guidelines. The REAL truth is that there are at least two distincly different chamber dimensions, the SAAMI spec and the SPC-II, much like the .223 vs 5.56 chambers. One Response to SAMMI pressure specs. The terms LUP and CUP represented a change in name only.
