Are the 7mm ultra mag and 300 ultra mag the same. Midway has the go gauge for the 300 but the no go is on backorder. They have a no go in 7mm ultra in stock.

Save your money. No need for anything but the go gauge. Meaasure everything up off the go or simply add scotch tape. Each layer is .002" .004" is the no go.
