Appreciate your comments. I think I was not clear. When I close the bolt on the cartridge I do so slowly and the projectile moves back into the neck with little effort. Definite no big push deal so don't feel I need at least with this calibre to do the dremel thing. Save that idea tho. So I have got to exactly the point you recommend. Then I have gone to my press and used the seating die to push bullet back a further 9 thou. And yes, I used a black sharpie marker to check. There is no engagement with the lands. At all. I am confident the bullet is 9 thou clear. I guess my question is whether 9 thou is enough? If accuracy is not there I am happy to keep moving the bullet incrementally back. I am ignoring the cannelure at this time. There is sufficient neck tension to hold the bullet and if I feel I need more I can use the Lee FCD to crimp the case at any point I desire. I understand Hdy putting the cannelure where they have as a universal positioning that accommodates a wide range of chambers and throats. But there is no law that it must be used, is there?
Anyway, I believe I am doing the process you describe but without the Dremel bit. Correct me if I'm still missing something.
