Optimum headspace

[carlsbad]

I'm installing a 6mmBR Brux Target barrel on a Remington 700 action. I assume that the optimum headspace is as close to the "go" gauge as possible. I adjusted it so that the GO gauge chambers easily. With a .001 shim on it, it still chambers easily. With .002" shim, the bolt will not close. so I'd guess I've got about .0015 over the minimum. I could take another .001 off the shoulder of the barrel if anyone thinks there is any advantage to tightening it up any more.

As usual, thanks in advance for your help.

Leave it right there.

Go shoot it. Work up a load and drive tacks with it

You are good to go. I set my chambers to .001" +- .0002" longer than headspace.

Thanks. That's what I thought but most literature addresses min and max rather than optimum. --Jerry
