Years ago I wondered what different fluxing made so I used a single cavity mould, saved all my bullets in their as cast order, fluxed every 15 minutes and then constructed a weight curve of all the bullet weights. What I found was that the fluxing interruptions invariably cause weight losses in the bullets cast immediately after the fluxing was done and that it took 5 to 10 minutes for the weights to restability. I haven't fluxed since.
During casting you want a temperature consistency. That is the most important thing. If you have to flux do it at the beginning or end but not during a casting session. Don't believe me? Just do the experiments I described and you can see for yourself.
Truth is that I didn't at first believe it either so I did that experiment several times. Eventually I was convinced.
