https://saami.org/wp-content/uploads/2019/01/SAAMI-Z299.4-Centerfire-Rifle-Approved-12-14-2015.pdf pg 110 shows a dimension of .3462
Anyhow....I can't figure out how to get the necks realigned. I don't have a FL sizing die for this calibre, just a body die and neck sizing die, and so can't correct the neck with the body in a die. So absent some better ideas from you good folk I either have to buy another tool/die, fire-form the brass again or dump it and start afresh fire-forming my box of Lapua.
I still have 12 unsized cases from the batch - the cases I used to side-by-side compare the extra thou of neck tension - which I haven't touched (only annealed). I will run them through my sizing dies checking each step to see if the problem persists (having cleaned the bushing/die and backing out the screw on the press).
EDIT: well I just resized one of these. It's not the body die. It's not the screw on the press. The deformation is occurring when using the neck die and with both bushings.
