Ive got a couple firearms Id like to try a bigger cast bullet in

My molds will cast a larger bullet..say .461...but I need to size to
..459

I have, lets say ,a lubricator/ sizer die that will do .457

Any good way to open them up .002?

One assumes that they are harder than hell, and I dont have a good way
to id grind them and keep out taper.

Any suggestions or ?

Before the jig grinder was invented, that kind of work (opening up
hardened drill jigs, mostly) was done in a lathe with a high-speed
internal grinder.

A Dremel in your tool post works.
