View Full Version : Dillon Square Deal 'B' press die threads
01-17-2006, 05:23 PM
Dillon makes the Square Deal 'B' press, it has four small threaded die stations. My question is...are the Dillon dies threaded 5/8 X 30, just like the old Lyman 310 dies???
Are the Lyman 310 dies usable in the Dillon SDB press.

I don't know for sure, but I remember reading somewhere they would work. It would be worth a try if you have any of the old Lyman dies laying around.

I don't know about Lyman 310 dies, but I just measured my SDB 45 ACP powder through expander die and got 5/8 X 16. The other die threads were buried in the tool head and I didn't want to readjust everything.

I've got Lyman 310 dies, but no access to a Dillon SDB press to try them for a fit.
Hope someone has.
The Lyman 310 dies work amazingly well for being so tiny. I find the seating crimp die is really great to adjust, must be the small threads.

Won't work. The threaded part of the diehead has to work with the inserts under the diehead. For example, the decapping pin assembly is threaded into the diehead but the carbide sizing piece is a collar held in place under the diehead which is attached to the top of the press.

Doc, you are so right. I looked in an issue of the Blue Press, it has two smaller die thread holes and two larger ones like the bigger inserts.
However, I think a reducer adapter insert could be fashioned much like the Lyman ones that allow 310 dies with 5/8X30 threads to work in 7/8X14 threads...a reducer is the word I'm looking for here.
Perhaps a reducer could be made to fit the SDB tool head where the larger insert dies go. Just a thought, but probably not practical.
Thanks for your imput.
