I guess I should have taken a reading on my 405 grain LEE .457 bullets I cast. I lubed them heavy with my castor oil lube and they ran through my my .451 sizer with little problem. I use a simple LEE press that the sizer is put into. They are a little stiff going in but actually not bad at all. Then I just collect all the excess lube that comes off the bullets and put it back in the tub. The ones that come out the top of the sizer into the collection chamber are lubed and ready to go.
