358 WIN.
The 358 Winchester (aka 9.1x51mm) was created in 1955 when Winchester necked up the 308 Win to seat a .35 cal projectile. Although it is a capable solution for hunting medium game, demand for the 358 Win has dwindled over the decades. At this point in time, Winchester’s own 200 grain soft point load is the only 358 Win ammo still in production.
