Reloading dies are the main, or the only thing you need to change, when you want to load else caliber. All LEE PRECISION presses use the same, standartized screw thread, that is identical with reloading presses of other brands.

Only exception in LEE PRECISION presses is LEE 50BMG press, which uses bigger size of dies (because of .50BMG caliber dimensions). But even this big and massive press contains bushings, which are used to allow this press to use standard dies.

Just one reloading press is using exceptional dies only, and it's DILLON PRECISION SDB. (Or at least it's the only one we know)
