I received a new expander with a new decapping stem for my Hornady .223 dies. The new expander is .002 larger than the old one. I measured 2 cases using each expander and the difference was .002 outside neck diameter.
Now since I can't shoot yet would there be an accuracy difference between rounds using the larger and smaller expander given the difference in neck tension?
I want to use the old one that will give me a tighter grip but maybe I should start with new one that doesn't have thousands of rounds through it. A trip to the range will tell but what are your thoughts?
