Are you measuring the variation on seating depth with the Forstner die on the Lapua 105s at tase head to tip, (COAL), or at the case head to datum line? My experience with the case had to tip of the bullet was =/- .005, but IMHO that is not the dimension that determines accuracy. I care a lot more about case head to datum line, (where the ogive contacts the lands). Thats the issue I had with the Forstner Ultra micrometer seating die.
So today when I reply to a post I see a button to "add attachment". Maybe I can post pics now. Something to do with paying to join?
