Re: Min or Max Saami Spec Reamers
Just to clarify... because this subject is of considerable interest to me on another front....
There is a SAAMI spec for the chamber dimensions, with a plus tolerance.
There is a SAAMI spec for cartridge dimensions, with a minus tolerance.
The idea is that (factory) ammunition that is at or below the maximum SAAMI cartridge dimensions should still pass into and out of any chamber that is at or above the minimum SAAMI chamber dimensions.
As a result, these 'minimum SAAMI spec' reamers are not truly 'SAAMI spec', but custom ground reamers that are at exactly the minimum chamber dimensions plus/minus nothing, correct? Or are they cut to maximum SAAMI cartridge spec? As an example, .308 Win min SAAMI chamber spec is listed as .344-346 at the neck (tapered), +0.002, but the cartridge spec is listed as a *maximum* of .343 (no taper)... which is a lot closer to what I see in some 'match' chambers - they pretty much start at .343 and go on down - .342, .341, etc.
