After my GCR rifle was kinda suces but unfortunaly very unacurate i want to build a presicion rifle.

see http://www.spudfiles.com/forums/viewtopic.php?t=1935&lighter=gcr+rifle& for my GCR



Now my new idea is a presicion combustion rifle for 300 meters so 'bought a 4,5mm rifled barrel from ...

how many meters is 50 yards?

whats that silver cilinder on the 5th picture? A co2 shelll?!!!!!!

the C:B ratio is much much biger than an normal spud gun so with some pure oxygen in combination with:

butane
Ether

it is kinda powerfull, with hairspray the projectiles often comes 20- 40 meter away with a ugly parabole. But im working on better fuels so stay tuned.

Yo should i use pure butane or butane from hairpray?

Thanks man 8) i always thougt iw would blow with a tine barrel

Made a new barrel today 12 mm diameter still dont know if im goign 2 use it for this one or for another one. Im scared the presure will be 2 big for an 12mm diameter barrel look for my combustion chamber volume on the top of the topic.

But fuck it, wicked experiments a great

Real fucking Awsome work man

I always used Hair Spray for my patato rifle cus it contains butane. How long do you guys spray in a tiny combustion chamber? But at the moment i only got deodorant in house. No .445 metal balls or patato/apple pieces.

But i got an second problem my bbq ignitor wich i use for the moment does not ...

Damn i tried serval times, just 1 lucky shot the bullet came somewhere 50 meters against a wall. Is very difficult getting the right mix into a tiny combustion chamber.

respect

on the background 2 of my air rifles

+ combustion chamber + compressor

i dont understand you, you mean the gun is 2 heavy comparing 2 the power?

I think if u use 1:1 Hydro Oxygen gas
Or special mixtures of propane/butane with pure oxygen i think this weapon will shoot far. Because of normal air is just 20% oxygen and the resting 80% nitrogen. So in in a combustion ...
