Thread: Subsonic action

they a lot like a .22lr on steroids .... 4times the projectile weight = more than 4 times the preformance.

From memory double the weight at the same speed hits with 4 times the force

Nope, double the weight at the same speed is double the force. The same weight at double the speed is four times the force.

Kinetic energy(J)= 0.5 x m(kg) x V^2(Velocity in m/s)

So energy is proportional to weight or velocity squared.

thats what I thought too, a quadruple. But iv been wrong before

Correct (well almost, m = mass, not weight, and our high school science teachers told us there is a difference).

If you throw some numbers in the equation you will see that doubling the mass doubles the energy, and doubling the velocity increases the energy fourfold.
