Absolutely. I still have those Shaw rifled 12-bore barrels, and was discussing this very subject (with barrels in hand!) with Vic P_ last week. There are a few unknowns with those barrels, ie rifling is only 5 thou deep, and the .719/.729 bore/groove dimensions will not allow much choke to remain if I ream the bores to .735 to fit my mold. Also, the Shaw tubes will clean up at around 24 1/2 inches which is fine for a bore-gun but too short for a 'pukka' Paradox.

I'm getting pissed off with seeing those tubes just sitting around though, and will probably do something soon. Because they are so thick at the breech ends, I'm toying with the idea of making them up with a dove-tail lump, so I can keep the original shotgun barrels. That was the main subject discussed with Vic.
