Sadly the Lapua 170 gr Lock Base has not been tested for G7 BC by Bryan Litz (at least it is not included in his book). Has anyone used it and found out by experience if Lapuas stated value (0.249) seems to be correct?

Lapua went back and recalculated their BCs downwards for most of their offerings. I think that they're more in line with 'reality', so I would plug in .249 for G7 and see what you see.

These things aren't absolutes and you need to confirm/verify what's what.
