Does anyone here know if the later modle rolling block shotguns have thestrength and overall size to be chambered in 12 ga I have been told the 12 ga are not really 12 ga and I wanted to build a 12 ga 3 inch slug gun on this it has been a on again off again thing but never got off the ground. Dont want to go to all the trouble to rebarrel if its going to be unsuitable. there is one gunsmith I have talked to said do it and another said a 20 ia all that can be done mine is supposed to be already in 16 ga but no markings to prove that any help will be appreciated

My question is about the action and barrel wall strength at the receiver. My 16 ga is not real thick in the barrel thread area and I was wondering if a heavier 12 ga barrel was threaded in would there be enough meat in that area to hold a 12 ga slug load of app 11,000 pounds I think that is what 12 ga slug loads are rated at
