After looking at the pic of the flutted 270 barrel of Mac's ( I WANT ONE BAD ) i think that they wold do a good business , maybe not great but good . with all the diffrent bore sizes that they offer the number of rounds that could be done are out of this world , it would only take a min. investment and would pay for itself in the first few years .
They have the barrel blanks , add a lathe , reamers and 1 good gunsmith , the options are unbeleavable .
