I quickly found the LEE collet case holder was never intended to house humongous 0.650” rims. Well….it is a lathe. So with Dick Lee readjusting in his eternal garden, I adjusted the limits of the mass marketed engineering. Slaloming on the glass now!
I decided to try trimming to 3” and ball expanding first. A trial (5). Looks to be nice resilient thick and long lasting brass.
