Peterson Cartridge Introduces the 7mm Shooting Times Western
 

Pittsburgh, PA (March 13, 2026) – Peterson Cartridge Co. of Pittsburgh, PA announces the addition of 7mm Shooting Times Western to its growing family of rifle casing calibers.

According to Derek Peterson, president of Peterson Cartridge, “We think of ourselves here, as being committed to Western Hunting and Western Hunters. Toward that end we produce casings for:

·       .257 Wby Mag	·       7mm Rem Mag	·       30 Nosler
·       6.5 PRC	·       7mm Wby Mag	·       .300 Wby Mag
·       6.5 Wby RPM	·       7mm Rem Ultra Mag	·       .300 Rem Ultra Mag
·       6.5-300 Wby Mag	·       28 Nosler	·       .338 Wby RPM
·       .270 WSM	·       .30-06 Sprg	·       .338 Win Mag
·       .270 Wby Mag	·       .300 WSM	·       33 Nosler
·       .280 Ack Imp   ·       7mm PRC	·       .300 Win Mag   ·       300 PRC	·       .340 Wby Mag

 

And today we are introducing our 7mm STW casings, for all the hunters who have an STW rifle in the cabinet, who struggle to find premium casings for it.”

In addition to producing SAAMI spec, standard dimension 7mm STW casings, Peterson also offers a version in what is called, “7mm STW Long.” Shooters of belted magnum calibers know that case life is shortened because the casing headspaces off the belt. As the case is reloaded and refired, it stretches in the chamber until the case head begins to separate. The solution is the “Long” version. These “Long” casings headspace off the shoulder like a normal bottlenecked casing. Because of this, the “Long” versions have a potential for many more reloads.
