Is there any reason why a chamber & throat "go" gage cannot be made by machining a solid or fluted piece of steel to the SAAMI chamber specs (including the compound throat)? Most of the dimensions could be verified with calipers or micrometers, so that should keep skeptics happy.
I suspect that the gage would need to be some amount smaller than the minimum SAAMI dimensions, but this needs to be left up to someone with more smarts and machining experience than me. In fact, if the specs are entered into a CNC machine, several of these could be made quickly and sold to those who want to use them on chambers. I am sure that they would fetch more money as presents for Grendel afficionados (you know who you are ). Think paperweight * ... but I digress
Of course, a chamber reamer could also be used, but I do not know if would be as easy (and inexpensive) as gage above.
Barring a better idea, ink or dykem could be applied to the gage which is then put in the barrel. If it does not bottom out properly, it could be gently spun to determine where the largest defect is.
How can all of the defects be found with one gage? Damned if I know, but someone else might.
No-go gages could be made as well, but the details of the compound throat might pose a problem for a single gage.
