6mm ARC

Even if we give them the benefit of the doubt with this “Grendel 2” misnomer, there is no .140” bolt face depth. It’s .136” (-.003” tolerable, not +.004”).

Every new cartridge seems to go through this reamer spec madness once the high volume production makers get a hold of it.

Once everyone gets in a tizzy, the reamer maker will announce their “fix” to the reamer design, call it theirs, and push their new name for it, adding more confusion.

It’s one of the reasons why I normally just wait for at least 3 years to let all the dust settle, or just have Manson make the reamer.

Getting ammunition manufacturers and reamer makers on the same sheet even with SAAMI specs is pretty difficult for whatever reasons.

Good points all

In my thinking if they say the bolt face depth should be .140 then there should be pleny of room in the chamber for the cartridge with a .36 boltface though .004 of the case might be unsupported.

As long as Hornady had with their press release being delayed due to COVID, and manufactures knowing about it months before the release and SAAMI specs available in March I see no real excuse about things being out of spec.
