Winchester Reloading Brass is manufactured to extremely tight tolerances to ensure smooth feeding and positive chambering. Consistent case-to-case weight and capacity delivers outstanding accuracy. Winchester&#8217;s high quality, durable brass can be reloaded several times. New, unprimed brass. This is not loaded ammunition.<\/p>\n<p><b>Brass Preparation:\u00a0<\/b>With bulk rifle brass you may sometimes notice a few case mouths are \u201cout of round\u201d or slightly dented below the shoulder.\u00a0 These imperfections occur in the final tumbling wash operation after the case mouth has been annealed.\u00a0 Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur.\u00a0 Minor dents are normally removed in the first firing and will not affect case life or performance.\u00a0 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.\u00a0 With some smaller caliber cases you may notice the case mouths to be slightly belled. Buy Winchester Brass 243 Winchester Super Short Magnum<\/p>\n<p>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. \u00a0To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass.\u00a0 To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth.<\/p>\n<p>If you are using Nickel plated brass, special care must be taken to lubricate the cases prior to sizing them.\u00a0 Nickel plating is harder than brass and the cases require more effort in sizing.\u00a0 In the event a case becomes stuck, purchase a stuck case remover; don\u2019t use pliers, screwdrivers or other common household tools which could damage your sizing die.
