6mm BR Redding S-bushings

[bpratl]

What is the best size neck bushing to start with using a new barrel reamed to SAAMI specs, with new LAPUA brass and new Reddings Neck S-dies.
I presently have a .267 bushing and the new brass measures a neck OD of .268.

I have the same set up- went with the .267 and .268 like you
