Caliber-specific pilot and reamer for the RCBS hand-operated Case Neck Turner. Machines inside and outside of .20 caliber case necks simultaneously for uniform thickness and improved accuracy.
Uniform case neck thickness is fundamental to consistent accuracy. The RCBS .20 Caliber Pilot/Neck Reamer delivers the precision you need to achieve it.
This caliber-specific tool is engineered to work exclusively with the hand-operated RCBS Case Neck Turner. It simultaneously machines both the inside and outside of .20 caliber case necks, creating uniform wall thickness that reduces runout and improves bullet seating consistency.
Factory cases often have inconsistent neck wall thickness. This variation causes bullets to sit at different tensions and angles, degrading accuracy. By normalizing neck thickness, you eliminate a significant source of vertical stringing and improve group consistency—especially important for precision rifle shooting and competition work.
If you're serious about handloading for accuracy, this pilot is an essential addition to your reloading bench.
