Not taking sides here but physics theories don't always say the same thing as facts. For example, airsoft and paintball. The reff at my local paintball field says that according to physics, since airsoft projectiles are smaller and travel at a higher velocity technically they should hurt more because more of the ballistic energy is transfered into a small spot on your body, whereas a paintball being larger in size and a little slower, not to mention the fact that they explode should hurt less because the force of impact is spread over a wider area. Yet so far nearly everything i've read from airsoft communites in multiple countries says paintball hurts more.
I can't say for sure cause i've only played paintball, but yeh. Thats just my 5c. feel free to poke holes in it

Anyways, i'm off to bed. L8rs all.
