Recently I've been researching the idea of more custom loads than just shooting factory FGMM and I noticed that several ammo makers will specify a COAL of say 2.80.
Out of curiosity I have some FGMM .308 168's and FGMM 7.62 175's and I measured the COAL and the .308's measure 2.80 but the 7.62's measure 2.81
Ever notice this?
