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.
Have you compared max velocity to a SS action on a similar build?I have a pierce titanium action, the bolt on it, just like on the defiance is made of 4340, not Titanium.

I have not. You're saying you saw pressure signs on the brass due to the titanium action with a Cromoly bolt? Before you saw pressure signs with a steel action?Have you compared max velocity to a SS action on a similar build?
Does it achieve a normal MV,without pressure? Mine had a CM bolt.
I've seen one that cost me 150-200fps and have a buddy on this forum that has several the same way…. It's no fault of the manufacturers.
When it's a problem it IS the material, is my theory.
I'm trying to figure out how that's relevant to a chambered round that is completely enclosed by stainless and cromoly.What flexes easier? Compresses easier?
Steel or Ti?
I went probably 500 on the Ti I had. 2 barrels gave the same result. So so precision and lethargic velocity.Without taking the same exact barrel off and shooting it from both actions or taking internal measurements of the titanium action, it would all be speculation wouldn't it?
Also Phil, how many rounds have been fired from the actions you are noticing this from? Just curious. I'm not an expert* as if I needed to state that.
So you had 2 rifles in 6.5max and with the same chamber, powder, charge, bullet and the titanium one was 200fps slower?I went probably 500 on the Ti I had. 2 barrels gave the same result. So so precision and lethargic velocity.
Took barrel #2, mated it to a Defiance Deviant, and not only was it significantly faster, it shoots better.
This group was at 200 a few days ago.

A 200fps difference in maximum velocity, 3350 vs 3150 basically.
