Hornady does not make the slides, Star made 1/2" powder slides and powder housing for the machines that needed bigger powder capacity, like the 44 mag, i cant swear that Star made them, others on here would know, Hornady makes the bushings for their pistol setup, these are the bushings that are used in the star 1/2" powder slides, I have also heard of 5/8" powder housings and slides, although i have never seen any, George.
