I have a pierce titanium action, the bolt on it, just like on the defiance is made of 4340, not Titanium.I'm curious to see if they cause/allow pressure signs to appear earlier than SS.
Between that and the fact that the bolt isn't titanium, so you don't have Ti on Ti, I've not seen any galling. It's not as smooth as a tikka, but there's no issues running it.Anybody tried one of these actions? I am curious if the DLC coating solves the titanium galling issues on other titanium actions.
