300 H&H Magnum

armcandy
Do any of you gentlemen use the 300 H&H Magnum?

I am looking for opinions on its effectiveness and if it is still a fairly well used round.

Thanks

    Friends and such of mine who collect and hunt with vintage arms and calibers hold the 300H&H in high reguard. It isn't in the same league as some modern 30cal magnums, but it still produces better velosities then the 30-06 and with modern powders on actions capable of higher pressures reloading can get good results out of it. The only thing that has kept it limited was the fact that it requires a full magnum action/box mag, like that needed for the 375H&H. With the advent of the 300winmag the 300H&H has been pretty much left to the vintage arms buffs.

    The 300 H&H is a fine powerful and accurate round. It falls within that class of cartridges known as "Suitable for all North American game".

    It's just a bit more powerful than a .30-06 and is probably more than you need for deer (unless at very long range), but a fine cartridge for moose, elk, bear, and other large game.

    It's a good cal. but because of the taper it streches cases a lot, not to good fer reloading, was designed fer string powder from bloody old England.[:0][:0]

    The 300 H&H Magnum is an excellent cartridge. I have been useing one in a Remington Model 721 since 1954. It will do anything that the short .30 Magnums will do. As it headspaces on the belt the long tapering shoulder/neck is not really a factor. The long neck gives better support to the bullet then does the short neck of modern .30 Magnums.
    As to case stretching, the .300 H&H doesn't stretch cases any more then do other .30 Magnums. All of them are subject to case stretching.
    Handloading is the best way to get the most out of the .300 H&H. The slower burning powders such as IMR-4350 and IMR-4831 will give the best results. All of the magunm .30's are at their best with heavier bullets. IMO, to use light weight bullets in any of the magnums is a waist, the original thinking behind the magnum concept was to give higher velocity to heavy bullets then could be obtained with smaller cartridges and at lower pressures. The British proved this point in Africa.
    The only reason that the .300 H&H Magnum is not more used today is the fact that it will not fit the "standard" length action. Other then this it is a very fine cartridge and has won a number of 1000 yard championships.
