Has anyone chronographed the speed of golf balls fired from their cannons. I plan on it but I need to get one first. I've used up to 700 grains of BP in a 24" barrel. The balls I use weigh about 700 grains. I shot it at my old house and the balls go through the outside wall and at least 2 inside walls of plaster and lathe. I found a couple of balls and they are hardly marked up at all. Any hints or tips or stories about your golf ball cannons would interest me. Thanks.
