Feed it H4350 until the chronograph reads 2700.
This is certainly a cartridge that a chrony is an absolute must. Anything else is just guessing.
Velocity tells you little except possibly trajectory from the tables. That's still guessing until actually tried on the range.
Of far more importance is group size from your particular gun and terminal performance from actual shooting of the load- at least for hunting game.
This is done by working up loads properly, for the individual rifle, not from choosing an arbitrary velocity value.
I have never used a crony, and the game I've killed or missed never knew the difference.
I imagine it could be a fun toy to play with, and certainly a requirement for professional writers, etc., and, if one HAS a crony, and is playing games with different components, and a particular rifle likes a particular velocity, that might be a good place to start when changing said components.
But a chrony is certainly not an absolute necessity, nor is a particular velocity.
