Lee bullet seating did .308

[Leatherstocking]

Wondering if anyone can tell me the pitch of the threads on this die. I’m planning to try different seating depths, developing a load for Barnes 150 grn TTSX.
Thanks

7/8-14 which is pretty much the standard except maybe for a couple of companies

I think he wants the pitch of the seating stem.

Yes, I’m trying to adjust the seating depth.

I used a felt marker to mark my seating stem in quarter turns. Each quarter turn is about 12 thou.

The pitch seems to be about 1.4mm.

1/4-28 thread is .036"/1 rev, 1/2-20 is .050"/rev, 1/4-27 = .037"/rev

Are you referring to the threads on the Lee-Loader [the depth is actually set by adjusting the length of the chamber] [don't own any any more, so cannot speak to that thread spec.], or the threads on the seating stem of the Lee Seating die that screws into a standard reloading press, which is 5/8 x 18 tpi?

20 threads per inch (TPI) pitch, resulting in
0.050′′
of seating depth change per full revolution.
