Personally, I wouldn't see any problem with him using it for the hunting season using 1 oz. loads from
www.rstshells.com, which 12s pattern beautifully.
Then pull the stock and forend wood, (if you don't know how, PM me and I will tell you) get a pan big enough that the stock will fit in, buy a gallon of acetone, put in pan,cover pan and let the wood soak for a couple of days or more until the dark spots of oil are gone or almost. It helps between soakings to put the wood on a sunny window pane to help draw the oil toward the surface. It's sometimes hard to get it all out. While soaking, turn the wood over from time to time.
When removing the wood have a rag ready to wipe it off quickly or you will get 'flash' spots from the quick drying acetone. let dry for a couple days; then some like to give the wood a wet wipe with rubbing alcohol before finishing; let dry couple more days and then I usually finish the wood with Truoil. You can do a search on this forum for finishing techniques. Look for Mike Campbells posts; he's very good.
The gun looks like it has the same receiver used on the Ugartechea Falcon. It may have 3" chambers like the Falcon marked 12/76; but I wouldn't shoot 3"; no need and harder on the gun.
