our last tests shooting walls, we tried
to line up 4 walls that were 2 feet by 2
It turned out that the 5.56 deviated so
much from its course after the first wall,
that it was almost impossible to hit the
other walls to test penetration.
So, we built bigger walls. These are 4 feet
by 4 feet. They are normal 1/2 inch drywall
or sheetrock, as it is called in some areas.
We spaced the walls about 10 feet apart
to simulate normal across-the-room distances.
We will be trying to see how many walls
will be penetrated by the rounds shot today.
