I found a website called "The box of truth " or the "Truthbox" or
something like that where they actually did tests like this by firing
into a box that had various stopping materials. At 30', the 00 shot
penetrated nearly everything. However, I am talking about 300' where
I assume the shot is going much slower.

You really need a rifle to make much of an impact at 300 ft.
