  • Pilot selection depends on matching the correct size to your cartridge; sizing charts are needed to confirm fit.
  • This is a single .358" pilot (#15), so it addresses one specific caliber range rather than multiple sizes.
  • The product information is limited to compatibility and sizing, so no additional performance or material details are provided.
