Keep in mind that those ballistics are only valid for general knowledge's sake, and may have no bearing on how the given cartridge will perform in your gun. There's nothing wrong with using published figures like that to "guesstimate" what a cartridge's performance will be like in your own gun, but ever since I bought myself a MagnetoSpeed chronograph, it's been pretty interesting to see how velocities vary between what is published, and what I'm actually obtaining right at the muzzle. That is one of the virtues of the MagnetoSpeed product (although it is danged expensive) is that you get the velocities right at the muzzle, and not 10' down range. Anyway, now I know what the terminal ballistics performance will be like, which is the part that really matters......especially for handloads, where I can choose a bullet that will perform best at the true velocities being obtained in my rifle.
