Re: TALK TO ME ABOUT POLISHING A SIZING DIE
polishing will increase the size so your neck tension will be much less.

Re: TALK TO ME ABOUT POLISHING A SIZING DIE
The amount of polishing to do to increase the final neck diameter of the die is.... You need to polish quite a long time. Full-length sizing dies that use an expander ball, like the Lee or Hornady, reduces the neck diameter quite a lot, letting the expander ball then do the expanding to the correct size. Once again, making it very unlikely that polishing the neck will cause a change in neck tension.

Re: TALK TO ME ABOUT POLISHING A SIZING DIE
I opened up a .429 Bullet Sizing die to .431.
However a Sizing Die is Carbide or in Hornady Titanium Nitride. Which is very hard.
Not sure if a Bullet Sizing die is also Carbide.
To open it I rolled it on piece of rubber. With Dowel through it and sand paper wrapped around it. It took quite sometime to go from .429 to .431
