300 Norma Magnum Case Lengths

[Bolt Gunner]

Hey Guys

Does anybody knows the Maximum Length and Trim to Length for the 300 Norma Magnum Case

Information will be greatly appreciated

I'm seeing 2.492 on case length.
Reloading manuals usually call for .010 under when trimming.
Don't know if that much is called for in this instance.

Thank you for responding. That's what I think also.

I thought I would resurrect this to add that I just measured 10 brand new Lapua brass out of the box:

overall length avg = 2.4833"

shoulder measurement avg = 2.0316"

Just for future searchers.
