Exactly - it depends on the type of powder you are using and the quality of your powder measure.My old Pacific measurer is great for flake powder like green dot and ball powder (WW296)but is too inconsistant with the longer extruded powders like IMR4350. All my rifle cartridges charges are individually weighed except the ones I load for the Stag M4. This I use Varget and my load brings the powder up to the base of the case neck. Its pretty easy to tell if I have a bad charge by doing a visual check.
