I need some switch barrel veterans to tell me if this will work to set my headspace to match my Forster FL benchrest dies to minimize brass fatigue and maximize case life. Caliber will be 6.5-.284 Norma.
I plan to set the barrel using a Forster go guage and tighten the nut. I have some ss shim stock, I will cut a piece and place between the bolt face and go guage to use it for a no-go.
Then I plan on shooting one round, and full length size the fired case. (new Lapua brass)
I will then reset the headspace using this piece of brass, and use a shim again to check no-go.
A few questions:
This proceedure GTG?
How thick of shim to use? ( I have all .001" increments available)
Will I realize any advantage? Should I just skip the headspacing to the brass and just use the guage?
