Can you open up the chamber of a 2 3/4" shotgun to shoot 3" shells?

I have an old Beretta a303 20 gauge and the barrel states 2 3/4" shells only, is it possible to have it opened up to shoot 3" shells? I really like the gun, but some areas I hunt are Steel Shot only and it is tough to find 20 gauge steel shot in the shot size I want in 2 3/4". I know I could ask a gunsmith, but I was curious if anyone here knew for certain or had done it.
 
It is probably more complicated than a simple SxS or over/under for two reasons.

1. The receiver must allow for the ejection of a longer hull.

2. Many Beretta's have chrome lined chambers and barrels. A special ream may be required.

Thanks for the input, I did not consider that. I have reached out to a gunsmith
 
Easy on break open guns. Depends on the auto. You would have to talk to a good gunsmith. I do know that guys used to do it with the 1100's and they worked fine.
 
Here is an interesting thread, https://www.trapshooters.com/threads/diffrence-between-a-2-3-4-and-a-3-beretta-303.150312/

If it were me it would be like taking your 12 year old hamster to the vet to get thousands of dollars worth of chemotherapy. I love berettas, and not degrading your gun. It is just the price for what you are getting and gaining would not be worth it. Good luck.
Thank you for the article, that answered a few questions. The gun has more sentimental value that actual value, which is why I wanted to make it more of an every day shooter. I have no idea what the cost to open up the chamber a little would cost, but if it is minimal, it could be about the cost of a case of shells which I have to buy specifically for this gun rather than the other 20s I have that will shoot 3" shells.
