I'm changing barrels from a 7mm-08 to a 22-250 AI. I'm new at this, so I took ya'lls advice, played safe and ordered Go, No-Go gages for head spacing the barrel.

Well, I got the Go gage, but the No-Go gage had to be back ordered. So, I thought I'd cut my wait time by e-mailing the manufacturer to see if they had one on the shelf.

The manufacturer answered me very promptly. And, suggested that If I had head space gages for a standard 22-250, I could use the 22-250 "Go gage" as a "No-Go gage" for the 22-250 AI. ??? Or, I could call and they would send me one.

All the headspace gage interchangeability charts I've seen have the 22-250 AI requiring "unique" gages. The word "unique" sorta' "means one of a kind". Now, the gage maker is telling me different.

I'm green at this, dumb as a rock. ??? Would/ could you tool maker guys help me out with this ?... Thanks.

Lin.
