Best example for bird vs buck vs slug is as follows.
Take a fist-full of sand, a fist-full of coarse gravel, and a rock, all of the same weight. Now pitch them at 90 mph (speed of a MLB fast-ball) at someone.
When that someone is hit with a fist-full of sand, they will say a few expletives, and will be very functional.
Throw the fist-full of gravel at them and they will say "oww!" have some bruises, some bleeding and be disoriented.
Throw that one rock at them, and now they are screaming expletives and are on the ground very not happy.
If you don't believe me, get a friend, some gravel, sand, and a rock and try it out yourself.
As for bird-shot acting like a semi-solid slug: It acts very much like a liquid. With each projectile acting like an independent object seeking the path of least resistance (hint: path of least resistance does NOT favor penetration. Human tissues are hard.)
+1 on Gryffydd. Do you really want to steak your life on a bunch of hits with 7ft-lbs of force? I think my BB gun puts out more energy than that!
