Following on from several comments on here prehaps some off our very experienced reloaders may reply to this.
Further to my issues in trying to get accurate and reproducable COL for my .223 69 TMKs i made up a dummy round and used the marker pen method.
To achieve this I had to slightly enlarge the neck dia to get the bullet to fit, it was snug. I read on here that all you do is place a bullet in resized, de primmed case and load, obviously it will be stiff. How do you do this if the bullet will not go into the case neck in the first place?
I have brand new Lapua match brass or FL resized lapua brass.
Also if you use the above method and the bullet is forced into the leade/lands how do you know if the bullet was cleanly pulled out when you eject the case, it might have been pulled fractionally out of the neck as the bullet was extracted?
