Description
Starline Brass 243 Winchester Unprimed (large Rifle Primer), Bag of 100
Introduced in 1955 by Winchester, the .243 Winchester is one of the most popular and versatile cartridges available. Derived from the .308 Winchester, the .243's low recoil and flat trajectory make it an excellent all around cartridge. Due to a wide bullet selection being readily available, the .243 can be applied just as well on the shooting bench looking over prairie dog town as it can waiting for a whitetail from 15’ up a tree. The 243’s accuracy potential is excellent making it a popular choice of competitive shooters. 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.
