Thread: Precision projectile seating

Alright obviously a straight round has a better chance of being "gooder" than one with runout.

A few years back I made myself a runout jig, none of my ammo was really bad for runout as I have always done as @Micky Duck does ever since starting reloading.

But I made myself a jig and separated rounds by runout and shot groups of each.....it is quite possible I cannot shoot well enough to see a difference.

I am rambling but this is the bit that will really fuck with your OCD

Where and how is the best place to measure your runout?
There are many ways to do it but some commercial solutions are not really conducive to ensuring everything is actually truly concentric.
EG
It is entirely possible to have a bullet held at the case head and projectile tip that shows no runout then show runout when held at the case head and shoulder.........
Happy sleepless nights.
