Running tests. The 230 grain Lee .452 RN/TL runs at 5 grains of bullseye easily. No issues there.
The Lee .452 TC/TL was stopped at 4.7 grains. It has a longer shank. I didn't push it beyond that.
The H+G .454 215 grain has a shank exactly the same length as the Lee .452 TC/TL. It is a regular design but will also be tumble lubed with the 50/50 mixture. (Liquid alox and Johnson floor wax.) I ran a few through the .452 sizer with no issues. I use that mix in my 40 S+W and regular lube grove bullets with no problems.
