Anyone figure out a workaround for the Forster co-ax and long dies? There’s a good deal on one locally, but I use SAC seating die, I’ve read the micrometer is too long and protrudes into the Y in the press arm. Curious if anyone figured out a workaround?
 
You can make a new handle, have another press or move to arbor seating dies. That's about your choices. I primarily use arbor dies...but I still have my original rockchucker I can use in a pinch.
 
I’ve got a Dillon 750 and Rock Chucker. Trying to get to a simpler solution, really focused on precision rifle and the 750 is more headache than benefit. I wonder what kind of clearance is needed, could you just grind a notch in the arm to provide clearance?

Not sure if you are aware. There are two handles for the Co-Ax. The old presses came with a shallow yoke in the handle. The new ones, guessing been out 10 years or so? Have a much deeper yoke. I don't have any SAC micometer seaters but the new handle clears the Forster and a few other brand mircrometer seaters I have.
 
The newer style yokes still don't work with all dies. Mine is 3 or 4 years old and won't clear a 7PRC Hornady micrometer seating die if seating long bullets to long COALs. It fits redding dies fine.
