Crossno liner

[JReed]

Here I am again digging up another old thread.
I have been looking at these liners and have a question. Does the rifles extractor engage the rim of the liner when opened or is the rim small enough that the extractor slides on by? Been reading about folks using them in 1874's and rolling blocks but no mentions of the extractor trying to pull the liner out of the barrel when you open the action. Just trying to wrap my head around how they work with the rifle. I am not familiar with the extractor on the 1874 but the rotary extractor in my roller is forceful if the liner traps the extractor I would be afraid something would break.
