Considerations & Trade-offs

  • Calipers are not included, so this kit requires a compatible measuring tool to use as intended.
  • The comparator is designed for headspace comparison rather than general-purpose measurement, so its use is limited to that specific reloading task.
  • It measures variations in brass before and after firing or resizing, which means it helps with setup and comparison but does not replace careful reloading practices.
  • The kit is sold without the body, so buyers need to confirm they already have the compatible Hornady Lock-N-Load setup or the matching components required for use.
