The success of dipping depends IMO upon several factors. The powder (small grained, low angle of repose, flowability), that is why it was successful with Bullseye.
Also the amount of the charge, small to very small charges work better, The shape of the dipper is a factor as well. Narrow dia dippers such as the .22 case have very little top area to heap, Bullseye a very low angle of repose, while striking off the top is an option it is not really required here.
I think that if I had to charge 1gr of Bullseye, I would make a dipper, and weigh the results.

In any case the proof of the method is left to the loader and his scale.
