Steve, I just received 2 30-30 blanks from Numrich yesterday. They were for a Mossberg mod. 472-479 @ 18.20 ea. Item # 586630. They are 18 1/4 long.
They look like shit on the outside and the bores looked like a sewer pipe and thought i was gonna have to send em back. Thought i'd take a chance and see if they'd clean up and they did. Bright and shiny and nice crisp lands.
Not sure yet about the O.D's yet at the chamber end because they are finish chambered and that will have to be cut off or plugged and rechambered because it's already too big for x25. I thought they were'nt chambered but they are. The rest of the barrel dim. are ok as they are all oversize for the AK parts and can be turned down to fit.
What kind of blanks did you order ?
