One action that comes to mind is the Nesika Bay action, one of which is designed for .223-size cases. It's a beautiful little action built from the ground up for precision. Below is a piece written by Lilja about this action. As for galling, Nesika handles this by making the receiver out of stainless and the bolt from chrome-moly 4340, and the result is a gall-free super-smooth action.Who builds a custom action around a 223 sized case?
