Crusher Manufacturers In India Rubber Conveyor Belt. Mar 04, 2015· So, you see in 7.62 NATO the M80 round has a peak pressure of 50,000 CUP (reported in the technical manuals as psi, even though, according to that article, the Aberdeen lab started using "CUP" in 1995 when the M11 copper crusher revision was put into service), and the M993 AP has a peak pressure of 55,115 CUP (3800 Bar or …

The newer M855 ammunition is loaded hotter and requires a longer throat that reduces peak chamber pressure back down to 52,000 cup. The following pressures below are exactly the same and are just measured differently using the copper crusher or a transducer located at different locations. SAAMI copper crusher 52,000 cup SAAMI transducer 55,000 psi

Is there a hunting rifle that shoots 7.62×51? The .308 Win "Go Gauge" is 1.630" vs. 1.635" for the 7.62×51. … No accurate conversion between copper crusher and true pressure exists, but approximations can be

Copper units of pressure Wikipedia OverviewMethodologyComparing unitsCUP and LUP pressures vs. transducer pressuresExternal links. Estimation of pressure using CUP and LUP units is performed by a special crusher gun, which uses pressure applied to a piston to crush a carefully manufactured and calibrated copper or lead cylinder.

The Winchester load guide data was developed at the time Winchester first switched to transducer pressure measurement instead of the copper crusher method. This load is milder than the factory 2800 fps load but was developed for using in the many old surplus rifles that were imported in the late 1980's and 1990's.

The manual also gives the pressures of the 7.62 CETME and 7.62 NATO cartridges, which I have converted to English units and compared to SAAMI maximums for 7mm and 308 Winchester. I assume the numbers given in the manual were measeured using the copper crusher (CUP) method available at the time.

The difference between CUP and PSI confuses me, but, again, IIRC, the .30-06 factory loads were in the range of the high 40 thousands PSI, but this would be PSI measured with a pressure gun using copper crusher pellets, and the PSI figure estimated, or calculated by how much pressure in PSI was required to compress the copper pellet a certain ...

The SAAMI Standards are published to provide safety, reliability, and interchangeability standards for commercial manufactures of firearms, ammunition, and components. SAAMI – Z299.1 – 2015 (R2018) — Voluntary Industry Performance Standards for Pressure and Velocity of Rimfire Sporting Ammunition for the Use of Commercial Manufacturers.

7.62x51mm ammo is much closer to .308 pressures than most people believe. The Armed Forces uses the copper crusher method to obtain their pressure date. SAAMI uses piezoelectric. Huge difference in the measurements even though the ammo is nearly identical. 7.62x51mm ammo will register close to 60,000 psi under the piezoelectric system.

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms.These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively.

My understanding has always been that 7.62 was lower pressure than .308. Generally speaking, he thicker case on 7.62 means less powder. This is somewhat counterintuitive since 5.56 is generally a higher pressure than .223. This should not be …

The real problem is the confusion between the old and the new methods of pressure testing. The old pressure testing method used for the 7.62 NATO cartridge started out life in the 1950s and is still published today in the US Army Technical Manuals. The figures are based on the copper crusher method in CUP, but are published as PSI.
