L. E. Wilson 300 Win. Mag. Chamber Type Bullet Seater


 Product Description

The standard chamber type bullet seater positively controls both bullet and cartridge case alignment. The case and bullet are completely captured by the die prior to the bullet being pushed straight into the case by a close-fitting seating stem. This style of bullet seater works more accurately than a conventional (7/8"-14) bullet seating die. This is one of the most accurate bullet seaters ever made. This seater is used in conjunction with arbor press. The die can be upgraded with micrometer adjustable seating top. L.E. Wilson recently introduced their own SS Bullet Seater Cap (our part number WIL-SBSC-MIC). Sinclair International has one, too (our part number SIN-749-005-419).

  1. 2.8200" every time

    Posted by NormB on 28th Mar 2015

    Using a Mitutoyo digital micrometer and a Hornady OAL gauge measuring base to Ogive on a 300 Win Mag load.

    In past years I have used Dillon, Lee, Hornady and RCBS dies, maybe one other I was so dissatisfied with I trashed or sold them ASAP.

    I kind of got used to seeing COAL readings with variances of +/- 0.003" or more. I say "used to" but not happy with. I finally, after many tens of thousands of rounds shot decided to try another way of loading since I'm not cranking them out on a progressive press but doing them by hand, I figured okay, I'll try this out and see what it does.

    I DID buy the micrometer top and I'm glad I did, because no matter how I fiddled with the set screw I'd still come up +/- 0.005 or more. Little half turn here, quarter turn there, load a round, mic' it, and so on.

    Turned the micrometer head 0.001" and cranked out ten rounds in a row EXACTLY 2.8200".

    How is this possible?


    Will it make a difference in an already 1/2 MOA gun? Maybe not, but once I've set this I can STOP doing the COAL checks on every single round, double bumping the press handle and all the other tricks to try and get them all the same length or very close to it.

    THIS is spot on. Very glad I bought it. And another for 308 Win and 223 Rem.

    i sold my Forster micrometer seaters. They just weren't getting it done.
