I may be missing something here, but exactly how would you use the Dillon with the actuator arm to throw powder with a LCT press? Maybe I've overlooked a way for the Dillon powder measure to be hand operated.
With the older Dillon powder measures (the ones with the springs) the actuator arm is only a safety device. The measure can be used without it as long as you pay attention and make sure it cycles fully.
I don’t think the OP said he was going to use the Dillon measure on the Lee press he was just comparing the two.
