244 H&H data

DEEREHART
Has anyone played with this cartridge much? It would appear as though it has the potential of being the king of the 6mm group. I can not seem to find much data except P.O Ackley.

    Its way over bore capacity. the 240 weatherby with modern powders is the king IMO.

    The 240 Weatherby might be king of the COMMERCIALLY FACTORY AVAILABLE rounds, as far as speed goes, but not as far as some of the wildcats out there...like the 300 WSM necked down to 6mm.

    DEEREHART,

    I think that the question is "the King of what?"

    I've shot stag with this cartridge and the bullet performance was everything I could ask for. The cartridge provided a relatively flat trajectory which was appreciated considering the distances we were shooting. This was using factory Holland & Holland ammunition, of course.

    The drawback here in the U.S. is finding appropriate bullets sized for the original .245" groove diameter. Naturally you can order H&H ammunition of the little use you might have for this type of rifle and cartridge but be prepared to pay dearly.

    If you choose to create a new barrel chambered for this cartridge then it's simply a matter of using a standard 6mm set of dimensions then loading with standard .243" bullets.

    We are fortunate these days to have a far greater selection of powders necessary for the large capacity cases. These powder have done away with the concept of a cartridge being 'overbore'. I have loads developed in a 26" barrel which are definitely not overbore and are actually quite efficient. This does dictate the need for the heaviest bullets and the slowest powders suited to the case and bullet.

    Hunting load start = 100 gr. Nosler Partition over 66 gr. Retumbo working up slowly, watching for signs of pressure.

    Match load start = 105 gr. Nosler Competition over 64 gr. of Retumbo working up slowly, watching for signs of pressure.

    Here are some other loads for your consideration:

    Nononsense thanks for the link its just what I was looking for. I had just posted the H 1000 question over on the reloading forum please dont think I am questioning your suggestions. As to "The King" it would appear that this may be one of the faster 6 mm factory cartridges out there. I have a soft spot for H&H caibers and this just looks like it could make a pretty good long range deer and antelope round.[:p]

    To build the project we would most likely use 6 mm dimensions on a model 70 action.[:D]

    Nononsense;since I do not have access to the original H&H chamber dimensions, what do you thing about the possibility that the chamber was built with significant freebore ie;Weatherby. The time frame is about the same that Roy was doing some of his most meaningful development with the 270 and 300?

    DEEREHART,

    I think that H-1000 is a decent powder for this cartridge, although it does not fill the case up as far as I prefer. No big deal though.

    Test away and let us know how things shape up.

    There is nothing wrong with having an affinity to a family of cartridges especially if it ends with H&H. I still hunt with a .300 and .375 H&H...

    How does the .240 Gibbs compare?

    tocamoha,

    Compare in what way?

    The Gibbs cartridge is formed from the '06 case while the .244 H&H is formed from the .300 H&H Belted Magnum case.

    Case capacity

    .244 H&H = 83 grains

    .240 Gibbs = 68 grains

    The differences noted for velocity performance are usually based on what the barrel length is chosen and the pressure level achieved for rifles chambered in the larger capacity cases. All too frequently folks limit themselves and the cartridge by asking for a barrel too short to allow the capability to shine. Most of the Europeans shooting the .244 H&H use 26" and 28" barrel which most Americans frown on. But then again the difference is where the hunting takes place.

    The older data for the .240 Gibbs is largely distorted by the desire to hotrod this design. Many loads are in the upper stratosphere of pressure when modern test equipment is used to check.

    Best.
