All of our presses, and just about all of our die sets, use 7/8"-14 threads, which is industry standard.
The only exception will be some large rifle calibers use our Large Series Dies that have a 1 1/4"-12 thread pattern. The only press capable of using these Large Series dies will be our Classic Cast Press. The Classic Cast Press is designed to work with both 7/8"-14 and 1 1/4"-12 thread dies, by means of a threaded adapter.
