Starline Brass 308 Winchester Unprimed (Large Rifle Primer), Bag of 100

The venerable .308 Winchester has made quite a name for itself since it was first introduced in 1952. The .308 and its military equivalent, the 7.62x51mm Nato, is a very efficient cartridge that has excellent ballistics, while still being fairly easy on the shoulder. That, and its inherent accuracy have kept it thriving as both a competition and hunting caliber. Our .308 case is slightly thicker than most other brands towards the base, giving it slightly less case capacity. This feature will allow the reloader to reduce their load slightly and still achieve the same velocity as other brands. This is not loaded ammunition.

Starline strives to hold the closest production tolerances possible on every caliber we produce to ensure the highest quality brass available. All brass is produced within SAAMI specifications and includes special heat treat processes and designs to enhance strength and longevity. This is not loaded ammunition.

Starline Brass prides itself on producing the highest quality brass case available. Their brass is comprised of 70% copper and 30% zinc and is vertically drawn during the manufacturing process which results in more uniform wall thickness. Cases are annealed between each draw to ensure consistent metallurgy in all lots. Each brass case is hand inspected to guarantee the highest quality possible.

Brass Preparation: With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder. These imperfections occur in the final tumbling wash operation after the case mouth has been annealed. Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur. Minor dents are normally removed in the first firing and will not affect case life or performance. On non-plated brass, you may also notice all the anneal stain might not be polished off, which may give the case neck a pinkish color. With some smaller caliber cases you may notice the case mouths to be slightly belled.

With all new rifle brass, you should first straighten out the case and case mouth, then chamfer and debur the case mouth inside and out. To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass. To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth.

If you are using Nickel plated brass, special care must be taken to lubricate the cases prior to sizing them. Nickel plating is harder than brass and the cases require more effort in sizing. In the event a case becomes stuck, purchase a stuck case remover; don’t use pliers, screwdrivers or other common household tools which could damage your sizing die.
