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’s high quality, durable brass can be reloaded several times. New, unprimed brass. This is not loaded ammunition.

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.

Winchester makes the highest quality brass available, and each and every piece is made to meet and exceed the most demanding quality control and performance standards in the industry. New, unprimed brass. This is not loaded ammunition.

Preparation:

• Due to the manufacturing process and/or shipping, case mouths may not be perfectly round. To ensure a round case mouth, cases must be sized (or have the expander ball of the sizing die run through case neck) and deburred/Chamfered prior to loading.

  Note:

• A light “staining” may be found on the case neck of new brass. This is due to annealing. Annealing is a process, performed by the manufacturer, which involves rapid heating to a specified temperature followed by rapid cooling. This process imparts cases with the proper hardness to securely hold a bullet as well as gives flexibility to expand and contract upon firing and repeated forming. The “staining” is a residue from this process. This stain may be removed by tumbling before loading. Brass should be full-length sized, trimmed and chamfered before loading.
