The chambers are 2 3/4 but cut for the fiber wads and paper shells or so I am told. The forcing cone is not a gentle taper like modern barrels but more squared off. I have not shot the gun as having read stories about modern plastic shells in the older chamberscan creat a problem with excessive recoil and harder on the gun.
That is why I was asking did not know if it was an old wives tale or fact. Wanted to find out a little more before taking it out I can load for it if necessary just want to do it right.
I had planned on using it as a donor gun for either rifle or bore gun but since it is in good condition and the barrels are good I plan on leaving a shotgun.
hope this makes sense
