Re: concentricity tools

I drilled and tapped holes into the 50x50x5mm shs and cut short sections of threaded rod and screwed them in.

It can be interesting when you discover some really poor ammo.

I have some factory stuff that doesn't shoot too well, one round measured .017 run out at the projectile.

I'm interested to see if/how much accuracy improves once all my brass is fire formed and neck sized compared to my fl sized rounds that have poor concentricity.
