Can a headspace gauge for 22-250ai be used to set headspace on a 250ai? Same family of cases
22-250ai and 250ai HS gauge interchangeable

I would assume so. A call to JGS would be in order.
On another note, I like more than .004 crush on parent case.

I used a PTG HS gauge last time I had the barrel on and this time want to use a Manson HS gauge with the .004 crush built in.

The 22/250 and the 250 Savage do not share the same gauges. Which means their AI versions do not, either! They are close, but not identical.
I like 22/250 minus .004 as a maximum length headspace, and this is typically normal. Minus .06-.008 is better where you bump the shoulder slightly on non-fire-formed brass to make a "custom" fit with the brand of brass that you are using. Headspace on new non fire formed brass will vary, great shock to some. My first 22/250 AI I had headspaced .025 short, which made for a longer neck to make up for the neck length shrinkage when the 22/250 AI is fire formed.
So, if you have a std 22/250 headspace gauge, the gunsmith can cut off whatever amount you want off the back so you will have your own custom headspace gauge, works great for help setting up dies and also in the reloading press.
