Did something similar to my non-CAS Ithaca 12 gauge. Put a barrel on it as short as the law will allow, with no choke, then swapped out the wood for a Choate folding stock with a pistol grip. Took it out to the woods to see how it would shoot like that. Set up a small watermelon on a stump and shot it, from the hip! The melon went "KA-BLEWIE!" I think the largest piece of melon that was left was about the size of a quarter.
Yep, got me a new "house gun."
