You are spot on with your findings regarding variety's. However using automated machine you don't have to skilled. After you did the settings for that case ( Case length to the burner because only the neck needs to be annealed ) and using tempulaq to get the right burning time you set the timer accordingly. Lapua cases takes approx 10 sec
The machine will burn each case for the same time duration at the same distance from the flame annealing each case the same

We did this a few years back and the machine didn't fail using a timer and the same burning point each time, a very skilled person did not had the same results doing it by hand..
