Load data for caliber "6 mm ARC"
The 6mm ARC (Advanced Rifle Cartridge) is a relatively new centerfire rifle cartridge designed for both military and civilian applications. It was introduced by Hornady Manufacturing in 2020, and is based on a modified version of the 6.5mm Grendel case.

The cartridge has a bullet diameter of .243 inches (6.17mm) and a case length of 1.53 inches (38.86mm). It is designed to be used in AR-15-style rifles, and is known for its versatility, accuracy, and moderate recoil.

The 6mm ARC is suitable for a variety of applications, including hunting, target shooting, and tactical use. It is capable of delivering accurate shots at ranges up to 1,000 yards, making it an effective cartridge for both short and long-range engagements.

The cartridge is typically loaded with bullets weighing between 85 and 110 grains, with the most popular bullet weights being in the 100-grain range. These bullets allow for high velocities and flat trajectories, which make the cartridge effective at longer ranges.

The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) is a non-profit organization that was established in 1926 in the United States to create and promote standardized specifications for firearms, ammunition, and components. SAAMI works to ensure that firearms and ammunition produced by manufacturers meet consistent and safe standards.

SAAMI has a broad membership base, consisting of over 120 leading manufacturers of sporting arms and ammunition in the United States. The organization is involved in various activities that are aimed at improving the quality of firearms and ammunition. Some of its core activities include the development of industry standards and technical specifications, testing and evaluation of firearms and ammunition, and promotion of firearm safety and responsible use.

One of SAAMI's key responsibilities is the development of technical standards for the manufacture and testing of firearms and ammunition. These standards cover everything from the design and construction of firearms to the materials and components used in ammunition. SAAMI's standards are widely accepted throughout the industry, and many government agencies, including the U.S. military, use them as the basis for their own standards.

One of the most important standards developed by SAAMI is the "Cartridge and Chamber Drawings" standard. This standard defines the dimensions and tolerances for the design of cartridges and chambers in firearms. This standard ensures that cartridges and chambers are designed to precise specifications, which helps to ensure safe and reliable performance.

SAAMI is also involved in testing and evaluation of firearms and ammunition. The organization operates a state-of-the-art testing facility where firearms and ammunition are tested to ensure they meet SAAMI's technical standards. SAAMI's testing procedures are rigorous and thorough, and they cover everything from pressure testing to accuracy testing. SAAMI also conducts research and development activities aimed at improving the performance and safety of firearms and ammunition.

In addition to its technical activities, SAAMI is also involved in promoting firearm safety and responsible use. The organization works closely with other industry organizations and government agencies to promote responsible firearm ownership and use. SAAMI also provides educational materials and resources to help individuals and organizations improve their knowledge and understanding of firearms and ammunition.
