Load data for caliber ".270 Win."
The .270 Winchester is a rifle cartridge that has been helping hunters bring down game since 1925. It was developed by Winchester Repeating Arms Company and is known for its flat shooting, moderately powerful capabilities. The .270 Win. moves a little faster due to its lighter projectiles and larger case capacity, which is basically just a necked-down .30-06.When brought to market in 1925, the .270 Win. was the best long-range big game round in existence. It shot flatter than anything else approaching it and had less recoil than other cartridges of the time. Today, it remains one of the most popular hunting rounds with versatile applications for both small and large game animals.

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.

Perfect caliber for mountain hunting
I love this bullet for mountain hunting. It shoots straight and delivers still enough force on a longer distance. My favourite for red stag and chamois in the Alps!
