to mesure velocity, i record sound with goldwave editor, well

the result is 89 to 97 meters / second, i don't know which units you use.
say it, and i convert if its necessary
edit 1 : it's 200 to 217 miles / hour

first arrow shooting sound, second the target sound, i know the distance between twice, it's easy to calculate.

Need to adjust for sound arrival times if the mic is not the same distance from both sound sources.

Excellent recording by the way. It is not distorted and clipped like most I've seen.

More info on audio is here;

Fantastic job! It is a bit visually jarring to see the SPAS-12 profile in "steampunk" texture as opposed to the matt black "tacticool" look but that's just a minor personal gripe, well done :D

Very nice, If anyone was to make a replica of Doc Browns Sniper rifle from BTTF 3, well.... it should be you.

Your Spas would look very nice with highly polished brass and a chrome silencer. But that's just my opinion, and everyones got one.

Still, great work and nice attention to detail!!

Nice!

One thing I just noticed about your cannon is that it fires with the slide pulled toward the user. "real" shotguns fire with the slide forward. Would there be any serious problems if someone unfamiliar with your gun fired it with the slide forward?

Not necessarily true.. The neostead fires when the pump is back, since it moves the barrel.
