I agree with Brian about the dispenser part. I have the Hornady. I5 was gifted to me or else I would not have spent the money on it. If it ever craps out. I will buy another. More likely than not the Lyman would be the one I buy. The only rifle loads I do not use it for I load with Trail Boss. For those I use dippers due to it being faster, and the accuracy is the same.
My beam scale comes out once a month to give a quick check on my dispenser scale as a cross check. So far the dispenser has been spot on.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
