300 Norma questions

[WeiserBucks]

I've got a new barrel on the way and have been doing a pile of research. There seems to be plenty of information regarding powder , bullets and brass . I can't seem to find the proper case dimensions, such as max length and trim-to length. Any advice?

I believe Wikipedia has case dimensions.

It's not in ansi/saami 2015.
But I found this, it's metric of course.

 

[tbrice23]

2.492" case length.
case length max 2.662"

If my metric conversation is right.

0.2" would be too much... difference in case length to max case length.

Typically, it would be a few thousandths shorter, for trimmed length.

The 2.494" would be max case length.

 

[tbrice23]

Sorry 2.492"case length.
Max 2.509"

Forgot a 0 on my addition.
The difference is .017".
Thanks

Again this is just from the PDF print out I found... nothing more.

That 2.509" is the actual chamber length.
