Gunsmithing 260AI Go/NoGo gages

[Cat64]

Can anyone guide me as to where can I find some of the gages in the title. At least the Go gage if nothing else. Thank you

Give Pacific tool & gauge a try. I bet they will have them.

I bought mine from PTG. Just the go gauge. You would use a standard 308 go gauge as your no go. I used my brass as a no go gauge. You want a slight crush with standard 260 brass so you can fire form without seating into the lands. Are you doing this for yourself? If so I could loan you mine.
