    Who knows.

    It can't be much in the grand scheme of barrel blanks, for $9.40 cents.

    I'd guess they are left-overs from some Black Powder company that went under. I doubt I'd trust them to far with smokeless powder.

    Also, I see no mention of rifling twist rate, which would be worth knowing.
    Could be for round lead balls.

    Makes sense, but the .510 barrel blank I got from that same company cost about the same and turned out to be 4140!
    When dealing with barrel pressures, it's ideal to know the actual metal grade and/or experiences of people using various loads with them.
