what does that have to do with anything?
"physics, gravity, and law enforcement are the only things that prevent me from operating at my full potential" - not sure, but i like the quote

you know you are not an engineer if you have to remind yourself "left loosy righty tighty"

What?

THIS is what he said:
I did some range shots with a relatively flat trajectory, I think I can shoot across the lake at good elevation (400m) but there's popular a hiking trail all the way around it so I won't try. The lake is about a mile long
A cannon that can do 400m is not bad at all. If you were meaning the 1600m length of the lake then I've yet to see the handheld cannon that can do a mile.
