In the land of the Fairies??Stupid comment I live in the LAND OF DRAGONS!, read the post on SD! 40gn .22WMR does out do 17 hmr at 100yds.
Energy
Velocity is an important factor in calculating kinetic energy, but so is bullet weight. We have already seen that the .17 HMR is by far the faster cartridge, but the .22 WMR shoots a far heavier bullet. Energy is important because it powers bullet expansion and penetration, and is a major factor in killing power.
Here is the energy of our comparison loads, in foot-pounds at the muzzle, 50 yards, 100 yards, 150 yards (when available), and 200 yard
