Here are some damage pics. I was shooting at a box fairly firmly stuffed with a sporadic mix of newspaper cardboard and low and high density Styrofoam.

The initial shot was a firm foam ball followed by a soft foam ball that was slightly heavier, then a regular golf ball.

All shots were at 80 psi or very near to that figure.

The golf ball exited the box and attempted to burrow into the ground before deciding to run about 30 yards and hide beneath a bush.

The golf ball dislodged the not-so-spongy foam ball by means of its immense concussive impact!

This is the entry wound just to the right of the previous shot.<br />This ball was made of a foam that is more squishy* than the other one, It weighed maybe a gram or so more.<br /><br />*scientific terminology

This ball was light and not very spongy, more firm than the other foam ball

Three balls in the hand, soon in the box!<br />The dimpled ball is the squishier of the two.
