There are 2 schools of thought on this...

Weighing the charge or using volume, such as a powder measure. Clint Smith did a test on this with a .308 and found that volume from a powder measure to be as accurate in any hunting application.

I have done the same thing for years and can hit anything I want with any gun I have and don't need a powder trickler at all. I even use a Dillon 650 for loading my 6mm PPC.

I figured that more people would pay attention to what a known shooter/writer would say, but I have had great success over the years with measured charges. I have a trickler I use for load testing, once the load is found the volume method will work every bit as well.
