Sorry for my long silence on the matter. As to basic info, I'm not sure what charge/ball combo was used. I had originally bought the gun at Friendship a few years ago. I see now that someone has identified the builder. I was going to Friendship this summer and was going to try to find the gentleman who sold me the gun. The only "operator error" I had ever had with the gun was accidentally "double charging" it during a shoot a year ago January. I was recovering from a concussion as it was so I knocked myself out on my feet. I was running a .600 ball with pillow lubed ticking and 65 grains of fffg. Shot it a lot afterwards. I'm not sure what the gentleman was using as far as charge and ball but we generally use the same on our trade guns. As more info comes to light, I will pass it on. I do want to thank everyone for there thoughts and appreciation that my good friend was unhurt. I am just sick over this. Although I didn't build the gun, I sold it to him so feel some responsibility.
