Have you read my theory about the right size bullet for any particular chamber throat? I did not make this up myself, I first read it in one of Mike Venturino's books. If you drop a bullet into a chamber, and it hangs up slightly in the throat, but light pressure pushes it through, it is perfect. If heavy pressure is needed to push it through, it is too big, if it falls right through, it is too small. Best done without any lube on the bullets, as they may make them a bit sticky and resistant to falling through. But if you have soft lead bullets that are a bit too big, like .454 in a .452 chamber throat, no a problem as long as the bullets are soft and the pressure is kept low, as with Black Powder.
I used to use a RCBS sizer to lube size my bullets. These days I use a Star. If all you want to do is squeeze them down a couple of thou I'm sure the Lee tool will work. Or you might think about buying a separate seater/crimp die for the different bullets. I keep several different seater/crimp dies set up for a couple of the cartridges that I load so that I don't have to change settings when I change bullets.
