I'v had three Whidden micrometer seaters made for modified cartridges. The lines on the micrometer are far enough apart my aging eyes have no problem adjusting by . 001 My Redding are so close I often guess. The Forster are easier to see than the Redding but not as easy as the Whidden. Most bullet seating stems are metal tunes that can leave a circular mark on hard seating bullets. My last Whidden has a hard plastic tip on the stem and i'v not seen any marks. My impression is that varying seating depths is due to varying neck resistance to bullet seating, not the die. Annealing usually corrects this .I didn't want to hijack the other thread about the sizing die so I'm starting a new thread. I am looking at getting the Warner Tool sizing die for my 6.5 x 47 I'm having built. My question is, which seating die is considered "best". I know you can get custom sizing dies but is it necessary for a seating die? I would like to stay with a die that will fit my Rockchucker press but would be willing to go with a Wilson style if it is truly better.
Thanks for any input
