We don't have any reason to shoot from farther out. Our shot gives us a range from about 8-18 feet. We focused on keeping the plunger super light so more of the energy can go into accelerating the ball and is not wasted accelerating the plunger. I'll get a better picture of our bearing setup for you when I'm in the shop, but you can see our outside bearings in the picture on pg 14. They capture the plunger on top and bottom.
