    Internal Ballistics Calculators

    I'd like to find a program that can calculate chamber pressure. Some manuals and websites will provide it but only for loads they've tested and all of them within normal parameters for a given cartridge. If you get a little 'outside the box' or simply have a component they didn't test you're in for more trial and error/educated guesses. For example; a rifle with a longer throat - what happens when the bullet is seated further out? Or a heavy-for-caliber bullet has to be set deeper to fit the magazine. The simple answer is "chamber pressure goes lower or higher," respectively, but I want to know how much it might deviate from standard pressures.
    Warning: I know Judo. If you force me to prove it I'll shoot you.
