I disagree that the exact dimensions of the throat are part of the spec. When you have a custom rifle built and if the gunsmith is a good one they always want to chamber to a dummy round. this is so they can set the throat. The throat is cut in a separate process. lets go pull a ruger, remington and tikka rifle off the shelf, in 308 winchester. would you expect there to be the exact or close measurement base to lands on those different rifles off the shelf?? with the talk that is around here about sammi this and that why even bother to measure the others?!?!

notice that all calibers have a neck diameter AND a throater you can spec in particular look at 6mm there are 3 different throats you can spec, with 6.5 there are 4 different choices in throat you can spec. Not all gunsmiths do it this way, for example a company like GAP rifles you must send or use one of their reamers which doesn't allow the neck and throat options, its fixed to whatever reamer that is because they do the whole thing in one process. things aren't always what they seem.
