FGMM & Black Hills Info.

[GhengisAhn175]

Wondering if anyone knows the cartridge base ogive length for 175 GR FGMM and Black Hills.
I know the cartridge's overall length fluctuates between 2.800-2.810 so I'm interested in the CBTO length.

This will vary from lot to lot, depending on actual ogive/bearing surface junction of bullet.

In my experience, it can vary up to .010 or more in the same box of ammo. They are not as consistent as I would like them to be.

I have both at home I can take measurement for you as a point of reference.
