Micrometer Seater useful?

[ButterBean]

Use a sharpie to make a line from the middle of seater stem to the outer edge. Calculate the travel per turn based on the threads per inch. It ain't rocket science to adjust to one or two thousands using the line you drew.

Why not? I seat my bullets all to +/- .0005 without adjusting the micrometer. The ones that are out of spec are fowlers . Your press setup and annealing and bullets have to be dead nuts to make this happen tho. I used to have couple tho variance and fuss with micrometer to seat to length on each.

Are you getting value out of the micrometer on a seating die?

Especially on a Hornady or Forster die which uses the same die construction for micrometer and non=micrometer dies….

I have both types and sort of value the micrometer, but in a Forster die, I'm questioning why.

I have the Frankford Arsenal Universal Bullet Seating Die with micrometer and get consistent results with it. Fits every caliber I own. It is easy to set up and use and makes fine tuning my seating depth a breeze.
