Thread: Using comparator tool when seating projectiles.

The Redding Instant Indicator is the solution that I use for producing constant CBTO ammo, it is set up using a known length dummy round. I seat all the projectiles between 4&5 thou too long with my Redding comp seating die and then run them through the instant indicator on a second press. This shows me how much I have to alter the comp die to seat the projectile to my desired depth. It is time consuming but makes for very accurate ammo.
