Sorry about that. Some reason I was looking at the cartridge OAL.My long charging die works just fine with the LEE Auto Drum and 30-06 cases. Something sounds amiss.
I have mine set up for 223 on the LCT. There is only about .800" thread left below the nut. Not sure, but I don't think I could do 30.06 on mine either. I use the riser. Don't remember the difference of not using the riser.
I did some 8mm and I'm thinking I barely had threads holding the die there.
