Nice build, looking at the stock you can tell it took some time that said it doesn't look very ergonomic or that visually appealing. Why did you cut the back part out?

You don't need an official record, the recognition you'll get from the spudding community should be plenty.

Although there are variables involved I'm bringing a 100ft tape measure to see if I can document anything measurable. That's not nearly long enough look up your shooting range on a satellite imager , I find that local.live gives better crisper images than google maps. Then find your shooting spot a...

Mmm blue :)

Looks decent could be a nice accent on a clear chambered combustion for the barrel and fittings or possibly some designs on the chamber.

While it may or may not be legal it's like rolling through a rural stop sign at 3 in the morning. Sure it's illegal but well you get where I'm going with this.

Just don't be stupid.

Your fletching looks a little small. I would make them as big as reasonably possible, maybe a spring out design or something that unfolds so the barrel diameter doesn't matter.

My first guess is that the air is leaking out slowly (relatively speaking) try pushing the pin on the schreader with a nail that so there's alot of area for the air to get out.

Basically I think the bb is blocking the airflow to much.

Why heat the air when you can just use higher pressure? I think it's because heating a gas raises it speed of sound so higher velocity's can be achieved. Without higher pressure, all of the stuff as to stay within the safety limits so lesser rated pipe is cheaper. I read the rules why don't you jus...

How much current do you have, and how much money? Nichrome wire comes to mind for this application.. It's commonly used for electronic ignition for pyrotechnics, 'muscle' wire and in applications like hair dryers. If you can get a spool of it fairly cheap, just coil it through your chamber on plast...

I would try for a massively long barrel and even pressure around the pumpkin. Maybe some small scale tests to see 1. What frags a veggy? If it's acceleration that can be solved with a long barrel 2. How does rifling affect soft ammo? How does rifling affect round pumpkins? How does rifling affect el...
