As previously stated, ball powders work the best thru the Dillon powder measure.
I use W748 and H380 for the .308 in my Dillom 550B getting very uniform charges from the measure.
That being said, when I load ammunition, especially for competition, I visually inspect every case receiving powder to be positive its in there.
30 rounds would not have been too many to check and it would have paid off on the line.
We learn more from our mistakes than our successes. Somebody said that sometime...
