Yes and no. An Ackely Improved round has the shoulder moved back just a hair further than a standard round. This allows the brass to have a slight crush fit and headspace off the neck and shoulder junction when fire forming brass. As long as you take this into account and adjust the die to not bump the shoulder and neck junction you can use a A.I. die as a neck size die.
