I'd bought one had they not made them illegal. That would be really fun from a boat with emptied/water refilled cans. By the time I'd learned of it -to late. Jet skiers to close and messing with my fishing spot could get a warning soda.
Currently I keep a long rod with a 3oz sinker tied on for the jet ski warning system.
I was running some numbers based on energy and velocity alone.
A 950 grain boolit at 1200 fps gets the 3k ft lb there abouts. I know that part. Turning that into a caliber that will shoot accurate & feed in a semi is beyond my current talent set. I'm working on it.
