    Because the exit hole diameter of the cartridge restricts the gas flow. There is going to be a point where the only way to get more gas into the barrel, while the bullet is there, is to raise the pressure or lengthen the barrel. It will take some pressure curves from both cartridges to give an accurate answer. Do you know if that data is available for public viewing?

    What is the case capacity of a 257 Scramjet?

    Great idea. You can also buy the inexpensive Weatherby 100 soft points for $ 34.00 to $35.00 dollars some time even less shoot and take a lot of game with it then reload the brass. It's great brass. I do this..
