I pan lube. Pushing them out base first never causes any lube loss. And I also use it fixed or breech seated. I've even sized some down for smaller groove barrels.

If you are going or want to size bullets like the Hudsons or bullets with any significant Steps or Tapers Pan lube them first. Then when you do  the sizing the lube supports the Bullet and it does not deform. Hydraulics of the lube wins out. 
I have sized Postell bullets from .460 diameter down to .451 diameter to get them to load like a Paper Patch bullet and they were beautifull and shot great with heavy loads of Black Powder. HTH FITZ, OLD TUCK

What Chris said.  The Hudson bullet was designed to be shot as cast and breech seated.  Lubing is best done in a hand held lube pump with an insert precisely cut for that specific bullet so no sizing occurs. 

If you are going to size it to a single diameter and shoot it from a fixed cartridge, you will be defeating the purpose of the Hudson design.  There are other Ideal moulds of similar design and weight that will work perfectly fine for what you describe. I would suggest you might try the 321232 for starters.
