I've been using a few of the Dillon lock nuts as well, primarily on the powder measure drop die (I forget the "official" name it is called). With the Dillon wrench, which is also small, and the small size of the nuts, it fits well between dies.
As far as the powder measure included with each Pro Chucker 7 die plate, I'd think one would only need the powder drop die for each die plate.
With my Hornady L-N-L and RCBS Pro2000, I raise and lower the powder drop die for different cartridges but do not need to make any other adjustments to the linkage of the case activated system to achieve full stroke.
