I am trying to buy barrels for a project,the project will be an 12ga.double slug gun.What i need to know would it be better to buy drills barrels or blanks?The second thing is the best place and who would be the best company to buy them from? And what is the best twist? I will contact E.R. Shaw this morning,so will someone help me?

I might have some in stock. PM me with your needs.
