Re: noobie sizer die question
Going by the Midway part # that you posted and xreffing to the Lee catalog (90374) is the Lee catalog number), you've got the .457" 405gr flat-base mold.
That one should use the 424 punch instead of the 374 according to the castboolits/castpics chart.
I don't know of the exact profile for those though...would have to ask a friend of mine who's not online. He does some .45cal casting for trapdoors.
Ahhh...res45 beat me to the punch...
