I have just changed to a 6mm spear on my 750 gun, hoping it will be quicker and a tad more range. In this context, i struggle with the logic of a wood gun (high mass / more power potential) and a thin shaft; it just don't seem right...
i like the idea of the rail gun, actually i really like the idea of a railgun, but the electrics could be suspect under water...
Railgun - Wikipedia, the free encyclopedia
"The U.S. Navy has tested a railgun that accelerates a 7 pound bullet to the speed of 7 times the speed of sound."
this could be something oh so beautiful
