Powder Measure or Scale for hunting loads?

[Adam Helmer]

A good friend insists on weighing EVERY charge for his .30-06 for his deer hunting loads. I began reloading in 1967 with an RCBS press and an Ideal #55 powder measure and a powder scale. I set the measure using the scale and test drop every 10th or 15th charge on the scale to ensure the measure is on.

Is there a need to weigh every charge?
