2023年11月7日 · Introduced in 2001 and intended for ranks of riflemen preferring 7mm cartridges, the 7mm Winchester Short Magnum WSM is crafted from the instantly popular .300 WSM case, necked down to accept .284-inch-diameter bullets. Also, the 7mm WSM shoulder was lengthened by .038 inch to prevent any possibility of chambering in a .270 WSM rifle.

Factory ammunition generates velocities roughly halfway between the .280 Remington and 7mm Remington Magnum. Hand loads tend to duplicate .280 Remington in order to extend case life. The 7mm WSM is an effective and emphatic killer of medium game out to intermediate long ranges, producing best results inside 700 yards, much like the .280 Remington.

The 7mm WSM and 7mm Rem. SAUM By Chuck Hawks Remington and Winchester went to short, fat, unbelted cases for their latest 7mm magnums, the 7mm Remington Short Action Ultra Magnum and the Winchester Short Magnum.
