35 Remington brass cases are carefully drawn from specially-alloyed brass to provide consistently exact internal volume and resistance to case stretching and brittleness. Primer pocket tolerances are held to .001″, and closely monitored case neck annealing ensures easier re-sizing and longer reloading life. New, unprimed brass. This is not loaded ammunition. Bulk brass should be full-length sized, trimmed and chamfered before loading.
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. 35 Remington brass

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 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.
