I'd be really leery about adding thin-walls to any gun, let alone one going on 150 years old. There was just a lengthy thread over at Upland Journal about the downside: http://uplandjournal.ipbhost.com/index.p...comment-1023843

Remember: modern/new gun, lead shot factory ammo, no problem with the ammo, unobstructed barrel (killed the bird he was shooting at, with the shot that burst his barrel), blew the barrel on the 3rd round through the choke tube.

Briley finally stepped up to pay for his new set of barrels, but only after he filed suit (he could afford to - he's a lawyer): http://uplandjournal.ipbhost.com/index.p...-20-gauge/&

YMMV.
