Neck sizing 6-7

[avidflyer]

Sizing a new batch of once fired annealed brass. This batch needs mostly 006 and some .007 neck reduction. I know over 5 should be done in two steps but this is so close I may just do it all in one step. Any thoughts? Also may try the expander ball this batch since I'm not neck turning....I know some say thats a huge no

A runout gauge will answer that question, it did for me.

The expander ball plowing back thru what you just sized precisely is the only problem. Other than that they work well.
