[QUOTE="Alibiiv, post: 1748756, member: 69192"] I would like to say that there are a number of variables that go into the formula for determining muzzle energy like bullet weight, velocity and distance "what distances are you trying to calculate muzzle energy". Take a light bullet, get it going at a high muzzle velocity and....at the muzzle the energy will be extremely high, but.....when you get out a distance that muzzle energy will diminish as velocity drops off. Where a heavier bullet will leave the muzzle not quite as fast, but....will hold the muzzle energy at longer distance due to the heavier weight of the bullet. What I am trying to say is that "feet-per-second" is not the only element in the equation for determining muzzle energy. Yes it is simple if one only measures muzzle energy at the muzzle, but....add distance to the equation and it gets complicated. Hope this makes sense to you? What [B]cohunt[/B] wrote in his reply to you about the Applied Balllistics app will give you about all the information that you will need to determine what cartridge does what when determining muzzle energy, muzzle velocity, drop and what to expect from a particular bullet (weight/design/ballistic coefficient) at a particular distance.
