Load data for caliber ".45 Blaser"
The .45 Blaser is a centerfire cartridge developed by Blaser in 2004 for use in their R8 bolt-action rifle. It was designed to be a high-performance cartridge for hunting big game at medium to long ranges.

The .45 Blaser has a bullet diameter of .452 inches (11.5 mm) and a case length of 2.165 inches (55 mm). It is a powerful cartridge capable of taking down large game like moose, elk, and bear at distances of up to 400 meters, with a muzzle velocity of around 2,800 feet per second (853 m/s) and a muzzle energy of around 3,600 foot-pounds (4,880 J).

The .45 Blaser has a unique case design with a rebated rim, which allows it to fit into a standard-length bolt-action rifle action. This makes it easier to handle and reload than many other big-bore cartridges that require a longer action.

While the .45 Blaser is not as widely used as some other cartridges, it has gained a reputation among hunters and shooters as a highly effective cartridge for long-range hunting. It is also used in some shooting competitions, particularly in Europe where Blaser rifles are more common.

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.
