Remember the data is a reference. Barrel length, rifling, twist rates even powder lot to lot can have slight differences.

Brass manufacturers, primers, COAL and OAL too can change your outcome. VVO 140 might, depending on year released, have the additives to be insensitive to temperature, barometric pressure and agents to remove copper build-up.

If you find there are major differences at 0 Centigrade and 34 Centigrade, try using the Enduron type powders. When confident, load up 20 rounds and test and test.
