Grendel II chamber

[bwaites]

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?!?!

here is a link to the reamers gre tan rifles has on hand

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.

You may disagree all you like, the facts are the facts. The SAAMI Grendel drawing specifies the compound throat, period. We aren't discussing custom .308 drawings, we are discussing a SAAMI specc'ed Grendel, and in that case, the throat is very specifically defined.

In the case of custom rifles, like my 7mm WSM, I spec'd the throat to shoot 180 Berger Hybrids and 180 Berger VLD's. The barrel maker gave me essentially the throat he would cut for VLD's, and because the Hybrids like to be further off the lands, I load them a little shorter and all is well.

But the Grendel is NOT a custom chamber, its a standard, SAAMI chamber. It should load every single factory round, just like a .308 rilfe from Ruger, Remington, Winchester, or anyone else will. Yes there may be slight variations from one manufacturer to another, but when was the last time someone posted that their new .308 wouldn't take factory ammo?

As I've posted elsewhere, I can load my heavy bullets out past mag length in my SAAMI chambers, without any issues.
