Great range results, unexpected velocity-- Pressure?

[Harvey_NW]

I'd load 43.5 and roll with it, because it should be far enough out of pressure signs to not have issues, and it's easy to remember using H4350. 3 shot samples from an OCW are statistically meaningless, you need a 10 or 20 shot sample at the same charge weight to extrapolate anything valid about the dispersion that load will produce.
