Load data for caliber ".300 Blaser Mag"
The .300 Blaser Magnum is an incredibly powerful and versatile rifle cartridge, developed in 2009 for use in Blaser's R93 bolt action rifles. This round combines the velocity and energy of a magnum rifle cartridge with the accuracy of a high-grade precision rifle - making it perfect for both hunting dangerous game animals like bears, buffalos and other large predators as well as match shooting competitions.

Offering excellent accuracy potential from quality rifles equipped with optics, this rifle round is capable of taking down even the largest game animals out to extended ranges while retaining sufficient power to penetrate through thick hides and bone. Its unique case design also allows it to be loaded with a variety of bullet weights ranging from 200 grains all the way up to 250 grains, giving shooters plenty of options when it comes to finding loads that work best for their specific application.

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.
