Water has the ability to create enough surface tension to feel hard when hit with another surface, such as your flat body. Bullets of higher caliber, when hitting the surface will lose their velocity because the minute it hit the surface of water, the force dissipated, rendering the kill factor less. Bullets of lesser caliber will penetrate the surface keeping more of it's velocity and also less deviance from it's original vector, hence, better killing effectiveness.
Look at olympic divers and how they are judged. If there is more body contact as they enter the pool, there is more splash. Which means a lower score. Better divers will decrease the amount of body surface area comes into contact with the water in order to create as less of a splash as possible, therefore a better score. It probably hurts them less, too.

Daniel's is the only one of the previous answers that is correct. The property of fluids that you are describing is called "viscosity". If enough force is applied fast enough (this is usually called shear stress), the fluid will resist flow.
Water is classified as a "Newtonian" fluid, meaning that the ratio of the force applied and the flow obtained is a constant: the bigger the force, the more resistance to flow, proportionally.

Yea, I'd of said Newton's law too. For every action there is an opposite and equal reaction. In this case the water is the opposite cause.

newtons law...for every action there is an opposite or equal reaction.. you falling at 5 f/p/s will cause a bigger reaction than at 2 f/p/s...the water doesn't have any special properties..

Water tension creates the water's surface. If you hit it from a distance then you can feel it smack against your skin.

Water is cohesive. Its particles form a somewhat strong barrier against penetration (which is why it's hard to split a drop of water).
