Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.

Product Information

.358 WINCHESTER (Large Rifle primer)

8.8x51mm

2.003 - 2.008 O.A.L.

Based on the .308 Winchester, the .358 Winchester was introduced by Winchester in 1955 for use in lever and bolt-action rifles.  While it had not seen the widespread popularity as the other .308 -based cartridges, its brush busting capability still makes it an excellent choice for hunting any of North America's big game.  With the recent rise in popularity of AR-10 style rifles, the .358 Winchester is starting to be chambered in it because the .358 gives the AR-10 just a little more thump than the .308 Winchester.

This Starline Brass is bagged at Graf & Sons. This is not loaded ammunition.

 Outstanding brass

By Frederick R. on Nov 09, 2025
Finding quality brass for cartridges is mandatory for top performance.

For less popular cartridges, this often becomes difficult.

Starline 358 brass is as good as any I’ve encountered. After running them through the size die and a light trim, the loaded round shows runout of less than .001”, with regular RCBS seat die. That is really outstanding.
