6mm BR newby neck dimension question.

[Rset]

My chamber is for 0.272 neck.
My resized, barely turned brass (0.012 thick) is 0.262 (standard FL dies)
My loaded ammo is 0.264
My fired brass is 0.269

From what I have been reading here, I'm thinking I need bushing dies, but what bushing? 0.266 or 0.267?
thanks!

Edit - turned brass is 0.012 not 0.0012

Double check those measurements, but if a loaded round measures .264. Sizing the case to anything larger than the finished OD will do nothing. Bushing must be smaller than loaded neck diameter in order to provide any neck tension at all.

I use a .266 for my .272 no turn. 6mmbra
I also have a 265 & 268.
I have found that my groups spread with tighter than 266 .

I use a .267 in my unturned Lapua blue box brass. It does fine. I bought a .266 just in case.
