So why don't all makers offer smoothbores in all the same sizes and calibers as rifled? I realize they won't sell a ton of them but it wouldn't seem it would cost them anything to make the option available. I'd like to build a smooth rifle with swamped full octagon barrel but the only smoothbore barrels I find are half or full round, that's OK, just not what I want. :boohoo: :boohoo:
