Energy Dissipation Steel Shot

[CCI]

Does anyone have factually accurate data on how steel shot loses energy over distance?

For example, let's say #1 or #2 steel shot, 3" shells, typical heavy waterfowl load.

18" slug barrel open choke.

What does it look like at 10, 20, and 30 yards?

Thank you, that is exactly what I was looking for.

Seems like there could be a legitimate and worthwhile use for a load that stays tight, has good penetration, delivers plenty of energy at 20 to 30 yards, and falls off fast after that.
