Three important notes about using your Forster Neck Reamer: Neck reaming should only be performed after the cases have been fired with a full load and before the neck or full length sizing operation. Wall thickness can be measured with a tubing micrometer, but a simpler test for excess brass in the neck area is to slide a bullet into a fired, unsized case neck. If you feel interference, the neck should be reamed or outside neck turned. Use neck reamers before resizing. Three exceptions to this rule are: P/N NR1220-.220Å" diameter reamer for .224Å" bullets P/N NR1239-.239Å" diameter reamer for .243Å" bullets P/N NR4275-.4275Å" diameter reamer for .429Å" bullet These are common sizes that reloaders use to ream their cases just before seating bullets. These three sizes are kept in stock for those who intend to ream after the sizing operation just before seating bullets. We grind many other special sizes as needed. Wildcatters often require specially sized reamers when converting brass from one caliber to another. You tell us the size you need and we'll grind it to your exact specifications. A nominal special grinding fee applies. Our quick turnaround service adds a versatile case preparation tool to your Forster Case Trimmer System.
