Depending on the brass neck measurements, I sometimes do. Is it necessary? Perhaps not, but I like the thought of consistency. I have used K&M and Sinclair turning tools and prefer the K&M. It's just a bit more comfortable in my hand plus it has graduation marks for making adjustments. Perhaps the newer Sinclairs have these now too, mine is pretty old. I do use the drill adapter with a low speed screwdriver type drill. It woks fine for me. I have not used the Hornady.
