Normal reloading die threads
Normal reloading die thread is 7/8 - 14. Does anyone make one that is 1 1/8-12 or 1 1/4-12? Got a press with a thread the is about that.

My old Rockchucker has a bushing that is 7/8-14 inside thread. I don't know what the outside thread is since I haven't removed it in a while. I think the Herter's press I used to have had a bushing, also. Without the bushing, it took a shot shell die. 0 -
As Ambrose noted a number of reloading press manufacturers make heavyduty presses with the oversize I.D. threads that you have noted. I've owned both a RCBS Rockchucker and a Lee with them. Hornady also makes one for specifically their Lock and Load bushings. To use conventional 7/8 14 dies in these presses you need a sleeve with the proper male O.D. thread, that has a female 7/14 I.D. thread. Try Midway, Graf's or one of the other large reloading tool supply places for the correct bushing. I know for a fact that Hornady makes one be cause I use it in my Lee press with their Lock and Load bushings. 0 -
Some of the old HD swaging presses used 1 1/8. I think Corbin and RCE still do. 0 -
My Lee .50 BMG press is 1 1/8". The dies will also screw into a RCBS Rockchucker with the bushing removed. 0 -
5mmgunguy,
Several 'O'-style reloading presses such as the Rockchucker use a bushing to step down for the 7/8-14 dies. The larger thread is based on the 1-1/8" dies for larger cartridges such as the .408 Chey-Tac and the BMG derivatives.
If you don't need the larger diameter dies, simply buy a bushing from one of the other manufacturers or have a bushing made to step it down to use the smaller diameter dies. Be sure to measure first and check the thread pitch. It's important to have the bushing fit correctly since the standard 7/8" dies will depending on two sets of thread fit for concentricity and perpendicularity.
