Ed,

Who makes 4 bore rifled barrels commercially? Any idea? The action that I would make, would basically be a scaled up H&R break action. Since this action is mine, and mine only, I don't particularly care if the hammer is rebounding. Although I may fit a rib extention with a Greener bolt for added strength. This is envisioned more as a fun project than a serious one, and more than likely strictly BP or equivalent.

So I ask again, who is commercially making 4 bore rifled barrels?

Thanks,
Scott
