If your press is single stage, as far as I know you should be able to use any brand of dies. I think there are some models of Dillon progressives that may require Dillon dies, but I don't have one so don't know for sure. 7/8” x 14 threads is pretty standard, so if you can find something that says that's what your press takes, just about any brand will work.What about dies? I have Hornady lock n load and a Lee single. Does the brand of dies matter? Will any brand fit in my presses?
Hornady dies and Lee presses are pretty much all standard (as far as I know) so other brands of dies should work.
