This is similar to The Holy Cows strategy last year but they used the pyramid as their aimer. Okay now to my question what angle will the arm have to be at if it is being shot by a surgical tubing punch that has 100lbs of pull back force when pulled all they way back. Sorry for the kind of lack of details but that is all the real information I have. Thanks for any help you can provide.

Unfortunately, you don't have enough details specified. For a spring-like mechanism the tension is: kx where x is the distance it's pulled back, but the energy stored is kx^2. So for a given force you don't always have the same energy, even in the ideal case.
