There has been a lot of talk about the damage caused by shooting mono bullets in double rifles.
I'm interested to learn more about any "specific rifles" which have been damaged in this way.
Have any members here actually had this happen to their own double?
Has anyone handled a double with visible overstressed rifling damage?
If so could you please post details on the rifle and load?
Does anyone have photos of this type of damage?

The Holland double that was regulated with mono solids and killed a barrel set, do photos exist of this?

I'm not trying to prove or disprove the overstressed rifling issue here.
The idea is to try and gather some first hand information on the subject from anyone who has actually experienced it.
