s12 22-250 conversion

[daveg]

I have a s12 in 22-250 that I want to re chamber to 22-250 AI. My gunsmith will have to rent a reamer so should he use a fixed or floatint reamer? Next howdoes one set the headspace on an AI chamber?

If your gunsmith doesn't know those answers I would look else where. I charge $75 plus shipping for a rechamber FYI

Floating is always the preferred choice. they just cost more.

Sinman has cut alot of A.I. chambers for me....really well I might add.

I will be contacting sinman but I stiil have the question of how do I head space the 22-250 AI?

[sinman]

Use a 22-250ai go gauge

[Carvera]

And a standard .22-250 go gauge, will work as your no go gauge on the AI.

I just pulled down the Clymer section on AI headspace gauges.. I use as my reference the Sierra load ing manual V ed. 4th printing. The difference between the 22-250 rem and the 22-250 Rem AI for the neck to shoulder dimension is .020 not .004 that clymer talks abaout so if this ids true a no-go gauge would not work!! If I have confused this let me know?
