wonko: are you suggesting that any metal removed to lengthen chambers or forcing cones makes a gun unsafe to shoot?
I'm not saying whether or not it is safe.
This was a cogent comment -
"You are talking about an unknown shotgun, with unknown barrel make up, re-done by an unknown personage of unknown skills and you want a finite answer, get a grip"
To me, for that very reason quoted, barrel mods of any kind instantly disqualify a gun from my interest. And I don't care whatever the reason may be/have been for it since most offered reasons are at best inane.
You, of course, may shoot whatever you care to.
