Saum Go Gauge needed asap

[lwing]

Hi there
Put all the parts together, lined up a smith, never even thought to line up a go gauge.
Any reccomendations where I can get a Saum one asap. I believe any Saum will work for 6.5 correct?
Thanks in advance

If the gunsmith can look up the saami specs he can make a gauge if he doesn't want to wait.

You can use a piece of brass in a pinch.
