Gunsmithing Chambering a .264

[xJohnBrownx]

Below is the SAAMI drawing for a .264 win.
Questions -

one of the notes says "All calculations apply at Maximum material conditions (MMC)".
Does that mean the drawings are for the maximum size of a cartridge and minimum size for a chamber?

I'm confused by the triangle symbol used, one of the notes says it equals "Reference dimension", can somebody explain that?

What is wrong with having my smith cut the chamber so a Berger 140 gr. with a base to ogive dimension of .700 touches the lands when the base of the bullet is flush with the bottom of the neck?

Am I correct in thinking that is going to put me about .104 longer than the minimum depth given in the chamber drawing?

Is this going to put me in a situation where only the Bergers will be likely to shoot well?

Is there a standard distance for this for this dimension if I don't spec it to fit the Bergers?

Thanks for the help guys.

Call Dave Kiff at Pacific tool and Gauge. Send him 2 dummy rounds and he will make a reamer off of those dummies. Now, just because he makes a reamer from those two cartridges doesn`t mean nothing else won`t shoot.

I understood that with a throating reamer you could set it to any depth you wanted without having to buy a new chamber reamer...no?

Pretty much, if you know what you want it's a hell of a lot easier to just get the reamer made that way in the first place, though.
