Micrometer Seater useful?

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.

I really do appreciate the responses. I have a handful of each. I question why I bought the micrometer dies, but each of us has our own methods. Thanks for the input.

I recently bought one of these units. Much to my surprise, they work pretty darn good. I seated a bullet and then adjusted the dial down to .005 and it seated the bullet exactly .005 deeper.

Micrometer seaters are the bomb.
I had a RCBS Gold Medal Match, Forster, Whidden and Hornady micrometer seater dies. Then one day came across someone selling a set of eight Redding micrometer seaters for $50. I snapped that up and now have a micrometer stem for every one of my Redding seater dies. For the ones that matter where I do not have a micrometer stem, I use the Frankford Arsenal Universal Bullet Seating die, like @newmexkid mentioned. It's a total rip-off of the RCBS gold medal match seater, but with a set of different stems and guide bushings for 1/3rd the price of the RCBS GMM seater.
[edit] The Redding micrometer seater stems are a different part number for each seater die. I would have thought them to be universal, but each of the ones I bought were a different part number, and as luck would have it, all matched the dies that I had. [/edit]
