I got it off the bolts lugs with the wire wheel on my grinder in just a few minutes. It came off real easy too so I'm not sure it's even Cerakote. It made a huge difference the bolt opens/closes easily and the bolts slides in/out easily. I asked my SIL what kind of stock it was and he said it was a custom stock that the gunsmith makes. It's actually a Bell and Carlson stock (I have 2 just like it), the gunsmith just removed material in the barrel channel to float the barrel.
That's how Cerakote acts when it's not installed correctly.
When it is installed correctly, it's pretty tough. Have several Cerakoted rifles I've hunted with a LOT that show hardly any wear at the corners of the muzzle crown.
You might try the wire wheel on an outside area of the barreled action. If the coating comes off as easily as off the bolt lugs, then it's either incorrectly installed Cerakote, or something else.
