Load data for caliber ".300 AAC Blackout"
The .300 AAC Blackout, commonly referred to as the "300 BLK" or "Blackout", is a modern intermediate rifle cartridge developed in conjunction with Advanced Armament Corporation and Remington Defense in 2009. Designed to provide increased terminal performance out of short-barreled firearms while still allowing rifle platforms to accommodate standard NATO accessories such as suppressors and flash hiders, it has since gone on to become one of the most popular choices among shooters looking for an effective short range cartridge.Offering excellent accuracy potential from quality rifles equipped with optics, this rifle round is capable of taking down large game animals like deer and elk out to 150 yards while still being relatively easy on your wallet. Select ammo manufacturers also offer loads specifically tailored to subsonic velocities - making them ideal candidates for suppressed applications where sound suppression is paramount.

C.I.P.
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.
