You have asked a question that can't be answered. There is no such thing as an "average" bullet. Define what you mean by "average bullet" and maybe someone can help you.

Slug could be a snail like animal. It could also mean one heavy bullet.
It depends on what you mean by "average impact."
If you mean how heavy is the bullet in a .40 caliber cartridge, the answer is, it ranges from about 150 grains to about 180 grains.
The 5.56 NATO comes in 55gr, 62gr, 72gr and 77gr. Bullet weight should be matched to barrel twist.
For a 9x19 Parabellum, usually 95 to 150 grains.
