Micrometer seating dies

Who makes the most accurate (screw into the press) micrometer seating die ?
Making sure the case neck is aligned with the bullet seems to be a fair bit important

No proof of most accurate but Redding Micrometer (Comp) dies does have the case alignment insert. Frankfort Arsenal also makes a Universal Micrometer Seater die that includes caliber specific inserts that are advertised as case alignment features as well. I own both and happy with results from each.

Hornday, seater with a micro adjust top will do a surprisingly good job.

I like my Forster dies.

Most accurate ? All the micro dies that various companies have will do the job. It just becomes your choice of which one to buy.

I have a Forster in a different caliber/cartridge .. The numbers are difficult to read. Combination of paint fading and old eyes. However it does work nicely

My favorite seating die is one I just bought. It is an RCBS Matchmaster.

The best micrometer seating die is a newlon blank reamed with your reamer

I'm more interested in the shape of the seating pin. All of them do not fit the tip of your bullet properly.

Yep
I hone mine a bit to get them playing nice with the bullets I run.
Mostly Forster with a whidden here.

I have several micrometer seating dies, RCBS, Frankford Arsenal, Forster Lyman. I find the Forster die gets me the most accurate #'s.

Redding, Hornady, and RCBS, they all work. Hone or replace the seater to fit your bullet.

RCBS Competition Seater Die!! If you can't find one in the caliber you want, find used, get the alignment sleeve from RCBS that fits your caliber. An extended shell holder will let you sear "short cases".
The earlier seaters had a "detent" in the Micro top. Good luck finding one of those.
Seating? It's a "feel thing". You fit it to YOUR chamber.

My $0.02… Redding or Forster will give you equally good results. Forster is usually a little less expensive and the dial is larger so it’s easier to read and finer adjustments can be made (the dial is larger diameter and the space between each 0.001” is greater). I would easily recommend the Forster. (But, either will give equal results based on every review involving direct comparisons I’ve read and my personal experiences).

Watch Eric Cortina using a wilson die. The measurement is from the top of the bullet seater holder to the bottom of the bullet seater, using a Vernier calliper.
