Did I say he shouldn't have his shotgun checked out? No. In fact I mentioned "modern ammo loaded to higher pressures than old guns can handle."
Again, NO tests have found any difference in pressure when 2-3/4" shotgun shells have been fired in 2.5" or 2.59" chambers. Read Gough Thomas on the subject, who published the info decades ago. But the same old BS keeps getting repeated, over and over again.
Just because you ALMOST saw a "short-chambered" shotgun blow up many years ago doesn't mean (much less prove) a short chamber was the cause. That line of logic is known as a false syllogism: A "short-chambered" shotgun blew up, therefore the cause was the "short" chambers. There are several other possible reasons, and based on what's been repeatedly proven about 2-3/4" ammo in "short" chambers, one of those would be the cause.
