We need a chart
Ask and you will receive!

Skoshi Tiger Pain V Bullet Speed Comparison Chart (c)
---------------------------------------------------------------------------------
................Ft/sec__Size of head (Ft)__Time to cover distance(sec)
Pressure____200___0.75____________0.00375
Pain_________3____0.75___________0.25
Mk7 .303_2445____0.75___________0.000306748
--------------------------------------------------------------------------------

This chart shows the time taken for the different item listed to propogate approximately 9 inches (very roughly the distance between the back of my head to the tip of my nose!

From extensive research of the first site returned by yahoo I found that nerve impulses generated by pressure travel at about 200 feet per second and those caused by pain go at only about 3 feet per second.

The trusty Mk7 .303 round travels at about 2445 ft/second (from memory!) (The Colt-Browning machine guns used the MK8 round but they were only a little bit faster)

As you can see there is an order of magnitude diffence between the time taken for the bullet to pass through the said distance and any feeling of the bullet. The pain is not even in the ball park!

Which leads to the old Joke

"what is the last thing to pass through a grasshoppers mind as he hits the windscreen of a car traveling at 60mph!?"
