.338 RUM Go/No Go Gauges?

You can save yourself some coin, no need for a no-go gage.
You can simulate easily with tape- two layers of .003 package tape trimmed to fit and stuck on the back of the go gage will be your no-go gage.
Bolt handle (with bolt fully stripped) should fall with no resistance (at most, slight resistance at the bottom of the bolt throw) on the go gage. If it falls with no resistance, add a piece of tape to the back of the gage and repeat. If it still falls, add a second layer. Bolt handle should not begin to fall.

This is done by feel- stripped bolt (no fp, or ejector) with a light touch.
