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

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.

Can you say Sunnen hone?
Piece of cake---capable of working to millionths in quailified hands.

I actually own a Sunnen. Not a bad idea at all. Ill have to see if the
guy is done using it, and if he left me any of the smaller tooling

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
