It penetrated all 4 walls.

This is the entrance into the last wall.

Looks like it was going sideways.

Time for the shotgun.

First a round of Remington Reduced Recoil 00 Buck that my friend ARKAN_the_Tiger sent me.

I have been curious about these rounds.

The Laws of Physics are unforgiving. You don't get something for nothing.

Reduced recoil should mean reduced terminal ballistics.

Sure enough, the recoil was obviously less than normal.

It penetrated all 4 walls.

This is the entrance to the first wall.

Notice the dents made by the plastic filler balls.

This is the last wall.

Quite a spread of 00 Buck.

Then a round of Hardened 00 Buckshot that my friend Blain sent me.

After the reduced recoil round, this one kicked like a Missouri mule.
