slug barrel blanks

[nostawpres]

Hello, Everyone I just picked up some Merkel double barrel shotguns cheap. Real cheap,
pitted bores ect. I would like to use these actions and mono blocks to build some very fine double barrel slug guns, would be a fun project, but am having problems finding
20 ga. rifled barrel blanks. E.R. Shaw and others say it will be in the fall before they have any more. Can any body out there give me some ideas on where to find barrel blanks. I would be grateful for any info.

You might want to try Badger barrels. I think they custom make rifled shotgun barrels.
