Thread: Rook calibre Identification

  1. #1

    Rook calibre Identification

    Gday All

    recently purchase a rook rifle that was supposed to be .360 Rook - it isn't.

    Bore cast reveals following: case length 1.19, rim diam .400"", base .346"and neck .345" and the rim was .046 thick.

    I cant seem find anything in Fleming or Hoyem that matches.

    Doesn't seem to be .300 rook or Sherwood either.

    So if anyone has any ideas or can give me the dimensions of their own rook rifles that are in the ball park
    it would be most helpful.

    regards

    You say bore cast but do you have the actual bore measurements?

    Typically, I've just travelled 400 miles away from my Cartridges of the World otherwise I'd love to be more help.

    Something to do with a 9mm Flobert? Could be totally wrong. The one I had could shoot the longer cases with fine bird shot and short cases with either 9mm ball or 9mm cone points.

    Does the bore have any visible rifling?

    That'll almost certainly be the .310 Greener (.310 Cadet) which was very popular in Australia as a training round (Martini I think). I'm not sure it is a Rook round as such, and is still loaded by Kynamco over here.

    You can shorten & convert .32-20 Win cases by skimming the rim, but the .32 Winchester Self Loading (discontinued c. 1920 sadly) is a much easier prospect.

    Just waiting for the exact verdict on the latter.

    If I'm going to be accused of it then it's just as well I did it.

    nope no 9mm Flobert - I have one of those as a garden gun for ball and a Win model 36 bolt action shotgun. Good thing
    Fiocchi and RWS still make ammo for them.

    yes those measurements above are exact bore measurements. The cast was done using a product similar to cerrosafe, very low
    melting point, put a wad about 5mm into the lands, pour the metal into the clean chamber (I use carby cleaner), wait 5 minutes
    and tape the cast out with a cleaning rod. The advantage of this stuff is that it expands to fit the bore and remains in that state for
    about an hour and then it will shrink a bit.

    The used use for dental dams as well.

    Cheers mate, I missread the OP. That .345" neck is throwing me. I'll be home on 30th so can have a gander then. What did the bore slug at?

    All the diameters are very close to the '32 Ideal', but the case length is closer to the '300(295) Rook Rifle'.
