Headspace Comparator Bushings

Headspace Comparator Bushings

Description

I didn't want to pay $30 for the comparator bushings so I tried to see if these could work. They are "good enough" to tell when you zero out on a case and bump the shoulder. The files with case names are sized to be accurate with my printer. The ones with numbers are straight to spec in inches (0.375, 0.400, and 0.420). I included a little hole size guide to see how close your printer is so you can mess with horizontal expansion.
