Had an old Stevens 12 gauge single shot I chopped once. Within 1/4" of legal minimum both by barrel length and OAL. Cut the barrel first and brought the stock as short as allowed after. It had the thumb lever across the top to open the action, and recoil would run that right into the web of my hand every time. I shot it with gloves for a while and sold it for $20(I had originally bought it for $10). I think that guy eventually took it apart and threw it in a lake.
More recently, when I got my .45-70 Contender barrel I bought a box of ammo, loaded it and held it out. Had just enough time before getting the trigger pulled to think "Do I REALLY want to do this?".
It definitely lets you know something happened but it's not as bad as people make them out to be.The deer I shot with it in December would disagree.
