Rcbs Pilot / Neck Reamer

The RCBS Pilot Neck Reamer is designed to remove excessive neck thickness and correct variations in case neck walls by working from the inside of the case neck. It gives reloaders a focused way to address internal neck interference that can affect how cases chamber and fit the bullet before seating.

• Internal neck reaming: Removes excess neck material from inside the case neck to reduce uneven thickness.
• Controls variation: Targets neck-wall variation so each case neck is more consistent with others in the set.
• Practical benefit: By addressing internal neck thickness, the pilot reamer helps improve uniformity in neck dimensions, which supports reliable seating and chambering.

Use this pilot-style neck reamer when you need a straightforward method to deal with uneven or excessive neck thickness. The design focuses on internal neck surfaces rather than external turning, offering a direct approach to correct neck-wall issues in reloaded cases.
