i'll run the numbers tonight if i have time. but i think the foot lb numbers you are using are for a Horizontal flight of a bullet in Air, at least they seem to match what my speer reloading manual says. (remember my premice is no air, no friction). with no friction there is no reason for the bullet to have lost any energy at 3000 ft hoz flight if it does not hit anything. where would the energy have gone? Newton's first law is: I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. so in vertical flight (no air) the only outside force is gravity. vfinal squared = vinital squared + 2as a = gravitational acceleration (32.2 ft/sec/sec or 9.81m/sec/sec) s = distance
Do you deny the formula? has nothing to do with weight or mass and is used in a frictionless enviroment if you would like and to keep others from knowing how pig head people can be we can continue by email.
