Acceleration is the rate at which an object changes its velocity, so the compression will lower the acceleration by some amount. By slowing the ball over an extra 2 inches, you have a smaller acceleration. With a smaller acceleration you have a lower force.
All that means is you need a higher starting velocity.

Sounds to me like you did a great job. As long as you can establish that your poof ball won't have to exceed the speed of light to punch a hole, it is possible.
two things you have to remember from physics:
1. F=ma
2. You can't push on a rope.
