Optimizing Air Cannon Range

At around 8:00 tonight my team (1726) tested a pneumatic tee-shirt cannon. We were overjoyed that the tee-shirt was launched, but found distance to be lacking. I am wondering if some of the members more experienced with tee-shirt cannons might be able to give us some advice on how to optimize our performance. Advice on how to fold the tee-shirts as well as any optimizations in our pneumatics systems would be accepted gratefully; we used the following pneumatics system.

KOP Compressor-standard tubing-7gal steel air tank-1/2in brass fitting-10' 1" braided nylon tubing-inline rain bird valve-2in fitting-3in cannon.

When the cannon fires it makes a sound resembling a large air horn.

On our test shot we fired at a 45 degree angle and simply stuffed the tee-shirt into the cannon barrel. We are unsure of the PSI because much of our stored air had been wasted in a previous shot and no one bothered to check the valve; however it is estimated to have been between 40-50.

Thanks in Advance for the help.
