It's the weight of the bullet, bigger grain is heavier, therefore harder hitting (more recoil) and more stopping power.

True, I guess mushrooming and bullet construction makes the difference. The heavier bullet will exert more force on the target on impact though.
I'm trying to find out what the different bullet grains mean?

Not true. Kinetic Energy = 1/2 Mass x Velocity squared. Any increase in mass (bullet weight) is linear wheras any increase in velocity is exponential. That's to say, if you double the weight of a bullet, the kinetic energy is doubled. But if you double the velocity, the kinetic energy is quadrupled....

Also, if you triple the velocity, the bullets *climb* out of the barrel.![]()

Dragoon, your formula is for Joules not for ft-lb! And you have to use Kg for mass vs grains, and velocity in m/s vs. fps. if you want to get energy in ft-lb and want to use grains and fps numbers. use this formula ME= mass x velocity^2 / 450400
Don’t want to turn this into physics class but you’re wrong; :|The units of measurement are irrelevant. The formula remains KE = 1/2 Mass x velocity squared
