Okay. I got my marker about 2 weeks ago (a Tippman 98 custom) and I'm having a blast using it. But I've noticed that about 30 to 40 feet out of the barrel, balls begin to behave erratically. Some do loop-de-loops, others simply veer off course. I recently installed a 14 inch barrel on mine, but aside from what appears to be greater ball velocity, the paint's trajectory is still warped. Is this because the velocity is too great, or are they not going fast enough.
