How is it possible for the muzzle velocity to be the same and the weight to be the same, but the muzzle energy different?Speer Gold Dot 40 S&W 180 Grain Jacketed Hollow Point Travels @ 985FPS with 400FT/LBs of Muzzle Energy.

I wouldn't have asked the question if it was a simple well known matter of physics.OK then agalindo you explain why there is different energy levels for all of those rounds I posted.
Exactly, but the bullets are supposedly the travelling the same speed.The faster the bullet travels it seems the more energy it produces according to your site references you posted.
Seems like the energies should be identical since the mass and velocity are the only variables.[TASF said:Overkill]
If the speeds are the same, and the weights are the same... how are the energies different?
