I decided to find a different gunsmith to set the barrel backspace with a Go gauge before I load and ammo for this rifle. This idiot set the backspace using a No Go gauge on a bolt face coated with Cerakote. If I load ammo for this rifle it with will have .089" backspace with the resized cases. If I had discovered this before I FL resized the cases I would have either neck sized or bumped the shoulder back .002". If my SIL bought were to buy commercial cartridges with the with smallest chamber allowed by SAMMI ( 2.0456") and it would have .0093" backspace. I'm measuring with a dial gauge so I could be off a little but it's right on when I measure the NO G0 gauge length. I watched many gunsmith videos on barrel installations in the last few days and every gunsmith set the backspace to .015" using a Go gauge. Brownells recommends .0015-.004 backspace for safe operation.
