neck turning question

[mason]

I have a new 6mm 6br barrel with a 268 neck what should the case neck measure without a bullet seated. The bullets measure 2435 on the pressure ring. ,lapua cases) and do i need to touch the sholders any??

Throat dia minus .002 = .266 loaded round neck dimension

.266 minus .2435 = .0225

.0225 divided by 2 = .01125 neck thickness

So .011 to .0115 would be what you are looking for. For a newbie you should probably shoot for the .011 dimension. Better a little loose than tight. Probably need a .264 or .263 bushing.
