    Haha. Nice one. The iron tubing is thick-walled, for safety I just assume it is mild steel. Mild steel is comparable to the wrought iron that smoothbore muskets were all made of. Hardenable high carbon steel was not used till the 1860s when the Bessemer process made this available on a large scale. Colt was one of the first to use it for his revolver cylinders which took hot loads, and from about the civil war on carbon steel was "it" for guns. Suffice it to say, wrought iron/mild steel is for black powder only.

    Hahaha @akaroa1 and I met a guy (up on Mt Peel) who told us the "best ever" Land-rover story. As I recall it he owned a late model Land-rover, something like a 2016 beastie. It broke down so he towed it into the Rangiora LR garage. After not hearing from them for a week he rang - "not yet fixed" they said. After two weeks he rang again - they said "come an tow it away, we can't fix it, and by the way, there will be a $4K bill" I think the aftermath was that the garage up the road fixed it for a further $500. This tells us something about Land-rover owners I suspect . . . .

    So I took it out after lunch as I'm having the afternoon off, and put 12 rounds through it. Id forgotton how much fun it is to shoot, and that I hadn't repaired the front sight after it got shortened a bit by accident.
    Target at 75 yards with 7 fired at it standing for the stunning figure of merit of 5.6
    The group has a 13 inch spread
    Yes I'd used the target before but figured out I could distinguish between the two by the size of the hole.

    @Cordite I'm thinking of going in the opposite direction to a junkyard steel muzzleloader

    4140 or 4340 steel barrels
    John at Vulcan can drill 4340 no worries
    So There is potential for very thin barrel walls due to the strength and resistance to barrel burst
    Lots of problems though
    I want .58 or bigger so need drills, reamers and buttons
    Or cut rifling and a bigger rifling cutter head
    And I'm also keen on gain twist so that's a whole other level of complication
    So what decade do I want to do this ?

    Sounds cutting edge a hundred or more years late. Not sure I can help you there. If you want to muzzle load and play with black powder you'd only need mild steel, you could purchase ready lengths of seamless steam/hydraulic pipe to reduce the amount of machining/drilling needed. Using a high grade steel for handling BP / cast boolits seems unnecessarily headachy ... but so is a lot of what I do myself. (-:

    "Minute-of-Redcoat". Is that with Minies or patched ball?
