Load data for caliber "6 mm B.R. Norma"
The 6mm BR Norma is a centerfire rifle cartridge designed for target shooting and varmint hunting. It was introduced by Swedish manufacturer Norma in 1996, and is based on a necked-down version of the 7x57mm Mauser case.

The cartridge has a bullet diameter of .243 inches (6.17mm) and a case length of 1.57 inches (39.88mm). It is known for its high accuracy, low recoil, and flat trajectory, and is capable of producing consistent, sub-MOA (minute of angle) groups at ranges up to 600 yards.

The 6mm BR Norma is commonly used for benchrest and F-class competition shooting, where precision and accuracy are the top priorities. It is also used for varmint hunting, thanks to its flat trajectory and high velocity, which make it capable of delivering accurate shots at longer ranges.

The cartridge is typically loaded with bullets weighing between 70 and 105 grains, with the most popular bullet weights being in the 80 to 90 grain range. These lightweight bullets allow for higher velocities, which translates into flatter trajectories and less wind drift.

The Commission internationale permanente pour l'épreuve des armes à feu portatives ("Permanent International Commission for the Proof of Small Arms" – commonly abbreviated as C.I.P.) is an international organisation which sets standards for safety testing of firearms. (The word portatives ("portable") in the name refers to the fact the C.I.P. tests small arms almost exclusively; it is ordinarily omitted from the English translation of the name.) As of 2015, its members are the national governments of 14 countries, of which 11 are European Union member states. The C.I.P. safeguards that all firearms and ammunition sold to civilian purchasers in member states are safe for the users.
To achieve this, all such firearms are first proof tested at C.I.P. accredited Proof Houses. The same applies for cartridges; at regular intervals, cartridges are tested against the C.I.P. pressure specifications at the ammunition manufacturing plants and at C.I.P. accredited Proof Houses.
