Hi, Patric! This is Super_Chuck from  Tekkro, and I have redesigned and extensively tested my cannon design for you. I had done 20 separate trials and with an average shot distance of 160 Meters and with a rare 1 block+/- right/left  aim  shift. I have the notes, data, screenshots, and  world save  on a google drive folder: https://goo.gl/0tsYP1
