Can someone measure the outside neck diameter of a loaded round with Lapua brass? I would appreciate it.

I'll swag it as I have a 20 VT reamer w .235 nk. It is supposed to be a no turn

Some are saying .237 neck is no turn with Lapua in 20 BR.

Mine are .232 loaded. .234 after firing. I did skim turn the necks slightly up on the shoulder after the first fireforming shot. This is with 40g vmax.

I had an offer of a new reamer with a .2355 that is why I asked.
