Hornady Comparator Set Organizer Box

thingiverse

For measuring CBTO, headspace and COAL, Hornady's Comparator series offers a range of measurement aids. They sell a bullet insert specifically designed for CBTO measurements, a headspace set to measure headspace accurately, and a wider anvil that can be used to seat case heads for COAL or headspace measurements. This storage box does not hold calipers of your choice or the Hornady/Stoney Point cartridge seating depth/comparator insert, along with associated cartridge cases. Instead, it stores: - Five headspace comparator inserts (A, B, C, D, E) - One anvil - A spare grub screw hidden under the anvil - The comparator body itself - Five bullet/caliber comparator inserts - A 1/16" hex key To prevent the grub screw from getting lost when tipping or dropping the box, use a piece of tape to cover and hold it in place. The pictures above show the grub screw uncovered, making its location visible. These measurement aids were previously stored in an older red Lee box with internal dividers that posed problems.
