Brass Preparation: Starline 45 acp brass

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

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 plate 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.
