I have the old Lachmiller luber/sizer. I bought a RCBS .401 sizing die for 40 cal boolits and the lube holes are too low in the die. I get a huge mess on the bottom of the boolit and no lube in the groove no matter the depth adjustment setting.
I want to drill holes higher in the die body and seal the ones there now. On my older dies the holes are a lot higher and work great, this die not so much.
QUESTIONS;
Are the lube dies hardened?
Can I drill these holes with a drill press? They are #30 in size and I have the bit.
Got any suggestions for sealing the old holes?
