I was looking today at 22LR on MidwayUSA and found some information I don't get. Aquila SuperExtra 22 LR 40 Grain Solid Point is listed at muzzle velocity of 1080 fps and Muzzle Energy 64 ft lbs. Federal Premium Gold Medal 22LR 40 Grain Lead Match is also listed at muzzle velocity of 1080 fps, but has a muzzle energy of 104 ft lbs.
How is that possible? Bullet's of the same mass, pushed to the same velocity, should have the same muzzle energy, shouldn't they? That's basic physics, right, F=MA? Is the website simply wrong? Were these measurements somehow specific to whatever different barrels these were taken in? School me please.
