[QUOTE="Remmy700, post: 1558559, member: 36564"] I found the best ES using bushing dies with expander completely removed. In most instances I can keep SDs below 5 usually around 2. While that is not the end all be all of gaining low numbers neck tension does play a great part of that. I have in the last few months went to using Sinclair expander mandrel with NT mandrel installed. Since I have done this it seems despite what die I use whether whidden, redding, forster, or hornady by adding the mandrel as my final step have been able to achieve super low numbers also. I can feel the consistency on bullet seating. As mentioned this neck tension is not completely the answer but a large part of the equation. The other large part is super consistent powder charge. I run a A&D Fx 120i and after moving to that from a chargemaster I also seen drastic drop in my ES numbers. With all this coupled together I feel as though I have found my recipe to making the best possible loads I can on my Co-ax. Despite the die on my bench, not a single one of them has an expander installed. [/QUOTE]
