The RCBS 9378 is a 22-caliber case trimmer pilot designed to work with RCBS case trimming systems. If you're setting up a 22 rimfire or centerfire reloading operation, this metal pilot is a precision component that guides cases through the trimming process with consistency. The tapered design helps seat the pilot smoothly into the case mouth, reducing setup time and improving concentricity—something any reloader who values uniform ammo will appreciate.
Case trimming is one of those easy-to-overlook steps that separates mediocre handloads from reliable ones. Cases stretch with every firing, and fired brass that isn't trimmed to spec can cause feeding issues, inconsistent pressures, and premature neck separation. The RCBS 9378 pilot is the business end of that equation: it's the component that centers your case and controls where the cutter makes its pass. Quality construction matters here, and RCBS has built this as a metal part that holds up to repeated use.
This is a standalone pilot—you'll need a compatible RCBS case trimmer body to use it (Rotary Case Trimmer, Trim Pro Manual, or Trim Pro-2 Power models all work with the right collet setup). If you're already running one of those platforms or building out a 22 cal reloading bench, the RCBS 9378 is a straightforward add to your kit.
