Got to do some casting today with the new NOE mold 200 gr swc 453 dia. All wa great until I went o size them in the lee push thru .452 sizer die. This is what I'm getting...YIKES. Pretty depressing, got about 500 of these now..Looks like they will be heading back to the POT.
No lube used.
What is causing this? When I ordered the MOLD I had folks say to order the .453 and size to 452. Now I got flashing on the bottom of the base. Bullets came out great sans that issue
Can't wait to hear this one....LOL
