Bushing Neck Die

[Steveu]

I lapped out the neck of my sizing die yesterday. Started with 280 grit for the first .007" and finished with some 400 for the last .001". It took me about 2.5 hours using a battery powered drill in a vice. It turned out great, the neck of an annealed starline case comes out at .428". My fired case case diameter is .432", so I have some room to do a little more if needed.
