    I have long been a fan of the old buffalo calibers and was wondering about a modernized version. When the 500 mag came out I never thought it could do what the big blackpowder guns could do. Then I did find some data on the internet that might sugest the 500 mag in a H&R handi rifle is the same as my 50-90 sharps in a 32 in barrel.

    For the same weight bullet 530 grains I saw data that produced the same velociety in both. 1425 fps. The only diffrence in the bullets is the 500 shoots a .501 dia. and the 50-90 shoots a .512 dia. bullet

    So the question is, does this make them ballisticaly the same? Will they have the same accuracey?

    Wild west guns made a leveraction in 500 mag
    H&R makes a single shot in 500 mag
    There is a slide action out there too I might have seen it on THR but cant recall.

    So are the 9mm and 44 magnum but there are plenty of rifles chamberd for them.

    Balistically they sound very similar, as for accuracy? Probably comparable - as always that will depend upon the rifle more than the cartridge.

    .500S&W can be loaded WAY hotter than .50-90 Sharps; this is a matter of standardized chamber pressure. The .50-90 Sharps has more case capacity, so it is much better suited for black powder usage than .500S&W.


    edited to add: the .500S&W is very similar to the .50-90 Sharps in external ballistics, when fired from a handgun. If you have a 32" barreled rifle in .500S&W, with some experimentation with varying powders, you could probably get some truly insane loads.

    I had thought to try a sharps action and make a 500 mag rifle, but some folks on a sharps forum I frequent say it cant be done due to the extractor and rim size. Its still a thought though. It is a definate custom build, maybe a bolt gun idea if the sharps cant work.

    I was thinking more of a 28-30 inch barrel.

    On a note I figured the 500 mag with a 500 gr bullet would hold 54 grains of bp making it only marginaly better than a 50-70 sharps. But with smokeless and the what seems to be limitless pressure capability of the 500 mag, I think I can well exceed the 50-90 and maybe even the 50-140.

    You can also get the same velocity with a 530 grain bullet in .45/70. The smaller bore diameter is irrelevant if you are using soft lead bullets because it will expand. The buffalo will not know the difference.
