Home Forums Hunting & Shooting Elk Hunting Enough energy for elk?

A 22-250 with a 55 grain bullet at 3600 FPS has 1582 FPE, a 360 grain WLFN flat point hard cast in a 454 Casull at 1400 FPS has 1567 FPE. That is less than the 22-250, is that your choice to stop a mad Grizzly Bear? Certainly is not my choice, yet the 22-250 has more energy. Energy can not be measure it can only be calculated.
In a collision energy is calculated in Joules, which is a heat measurement. Why is that? It is because FPE transforms into thermal energy (heat)

1 Joule is equal to 0.737562149 FPE
