The American Chunker Air Cannon team has reported that their machine will have an automatic firing capability. That is amazing.
American Chunker:
THE FIRST EVER FULLY AUTOMATIC CHUNKER -- Coming soon..........Team American Chunker goes "Fully Automatic" Well ...close (15 round burst capable). The crew will soon unleash an absolutely unbelievable show of power. Shock and Awe would be considered an understatement! Stay tuned as this innovative group paves the way for the future of high powered air cannons. The US service rifle commonly know as the M-4 or M-16 shoots a 3 round burst, wait till you see this soon to be World Famous air cannon demonstrate what a 15 round burst looks like on an unsuspecting junk car! This is the first cannon to ever attempt this successfully. One of many firsts I suspect.
There are now only 74 Days, or 10 weeks and 4 days, until you get to see this amazing machine at the Second Annual Vermont Pumpkin Chuckin' Festival, on October 3, 2010.
