A powder measure & ball powder is all I have ever used. Ive loaded over 90k rounds this way and spot check about every 25-50 throws and my scale says no change. I fill at about 2/3s low on powder.
I dont load one at a time, I fill 300-500 cases at a time, good lighting to insure no misses and insert my bullet.
Not one problem to date & never a missed case of powder.
I dont shoot in competitions otherwise I may do it another way.
All my drops have been very solidly consistant and when I test on paper I get clover leafs. That says to me do not change what I am doing.
I tried an electronic dispensor a whlie back & for me its wayyy to slow so I sent it back.
