All this is fine, but, if they don't have the tooling for the dies the OP wants [222 mag 45*], they may or may not be able to make them for him. He will still have to have fired cases or a reamer print etc...
I found the basic die for this round here: http://www.ch4d.com/catalog/dies/caliber-list?page=9
The tight neck issue can be resolved by calling CH4, and discussing what he needs. I posted this link, and another on his other posting about the rifle, but no interest.? Is there something wrong with CH4 dies?
