Last comment for the moment on this thread.

This has been studied forever. I have an American Rifleman article from the 1930's concerning shotshell pressures and chamber length (among other items) as they were setting up SAAMI.

No one has mentioned cost. 2 1/2" shells are not common on the shelves of American gunshops. Having them delivered to your home is prohibitively expensive for many of us. Particularly when we have already stretched the budget to its breaking point to buy a fine older gun.

In fact loading LOW PRESSURE shotshells is one of the few areas of reloading whre you can still save signifigant money.

Of course you can (and I have) trim hulls to 2 1/2" but this adds time, cost and complexity which can quickly make the process not worth the effort.
