I have just the gun for you. It's a 10 bore , 3 frame Parker that Simmons sleeved, chambered for 3 inch 12 gauge and added their vent rib to the 32 inch tubes. They retained the 10 O.D. on the tubes. So if you are a good strong guy it's just for you. You could then become the owner of the world record Parker. After the massive barrels it has been torched for color and a MC stock added. The ultimate record holding pimped out Parker.
With choke tubes it should handle steel with ease.
