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.

Internal ballistics programs assume that every kernel of powder in the case starts burning at the same time and burns at the same rate. Given that the rate of rise of pressure in the models is generally very similar to what is seen in pressure guns, this is a pretty good assumption.

Feb 03, 2017 A single copper indent crusher is placed in the firing chamber of a firearm and the trigger is pulled, causing the firing pin to strike and leave an indent mark on the rim area of the copper crusher. The copper crusher is then removed and the indentation measured (Fig. 6). The indentation must measure 0.014 inch (read to the nearest 0.0005 inch ...

Internal ballistics, a subfield of ballistics, is the study of a projectile's motion from the time its propellant's igniter is initiated until it exits the gun barrel.1 The study of internal ballistics is important to designers and users of firearms of all types, from small-bore Olympic rifles and pistols, to high-tech artillery. 1 General concerns 2 History 3 Priming methods 4 Propellants 4.1 ...

Sep 14, 2012 Bullet Ballistics: Velocity. Measuring gas pressure proved as difficult at first as measuring bullet velocity. Then, in the mid-1800s, Alfred Nobel and an American named Rodman came up with solutions to that problem at the same time. Rodman’s, the crusher system, is still in use. Cases of rimfire ammunition are thin, limiting pressures.

Most folks who shoot or reload ammunition have heard of the Sporting Arms and Ammunition Manufacturers’ Institute, Inc., or SAAMI, but few know how it came about or the extent of its support for the firearm and ammunition manufacturing industries. When I came to my current position in 2011, I soon learned there was a lot about the organization that I didn’t know.

Jan 04, 2011 Powley and Hutton referred to the measured values as pounds per square inch, but it actually wasn't. Today, copper crusher values are called copper units of pressure (CUP). Unfortunately, there's no reliable method to accurately correlate psi and CUP, but that's a topic the ballistics editor can expound upon better than I.

Oct 13, 2014 The other fact, which I think is the main problem, is that the deformation of the crusher gauge is a record of the total force on the gauge over the entire internal ballistic cycle, not just a measure of the peak. Cartridges may have the same peak pressure, but different cycle times, so the total force and hence gauge deformation varies.

Apr 18, 2015 A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.

The 6.5×55mm Swedish (also known simply as the 6.5×55mm) is a first-generation smokeless powder rimless bottlenecked rifle cartridge.It was introduced in the 1890s, and is still one of the most common cartridges in modern rifles built for the Scandinavian market today. The cartridge was developed in a joint Norwegian and Swedish effort starting in 1891 for use in the new service rifles then ...

Wound ballistics is a facet of terminal ballistics that describes what a bullet does after it hits hair. Bullet manufacturers advertise the wound ballistics caused by their bullets by tossing around phrases like “knock-down power” or “devastating terminal performance.” Yet understanding how a bullet accomplishes those feats can be tricky.

Gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. Pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. However, crusher pressure deformation at high pressures deviates from the corresponding values measured by ...
