Starline Brass prides itself on producing the highest quality brass case available.

Brass Preparation: With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder.  Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur.  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.
