Sold in bags of 50 factory new STARLINE unprimed 358 Winchester brass rifle cases.
Notes: Winchester designed a “woods” cartridge that would fire a 200 grain bullet at a similar velocity a 300 savage can propel a 150 grain round. Based on the 308 Winchester, the 358 Winchester was introduced in 1955 for use in lever Model 88 and inn the Model 70 bolt-action rifle. Currently the popularity of the AR platform has given the 358 Winchester a second look for the shooter wanting a heavy hitting cartridge.
Brass case mouths MAY not be perfectly round from the manufacturing process, this can be corrected by running brass through the size die (always recommended) prior to loading. Residue from the annealing process may leave a stain on the case neck that can be removed by tumbling. Annealing involves rapid heating then cooling to impart the shell cases with the proper hardness to securely hold bullets in place and provides flexibility to expand and contract through multiple firings handloaders expect.
