Load data for caliber ".325 WSM"
The .325 WSM (Winchester Short Magnum) is a rifle cartridge developed by Winchester in 2001 for use in their signature line of rifles. This round offers increased performance over other cartridges such as the .300 Winchester magnum with velocities up to 3,400 fps due to its short and fat design, resulting in less muzzle drop and flat shooting trajectories at longer ranges.

The .325 WSM is an excellent choice for those looking for a light-weight cartridge suitable both big game hunting and long range target shooting given its impressive ballistics. It has seen limited popularity compared to other calibers from the same era due to its relative rarity, but can still be found if you look hard enough.

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.
