Talking about Lee boolit sizers specifically, but anything similar will help.
What are the best ways (read - best results) to open up a sizer body to get a larger finished diameter?
What kind of surface finish is best, super fine polished, or less spectacular?
I'm talking going up a few thou from a standard size, .429-.432 or such. Who tried what, what works, what does not?
Thank you kindly.
