burst-disc breech loader

[huse_spud]

This is my combustion launcher. It's small, portable, and powerful!!!

costed less than $20 to build.

What are you makeing the disc out of?

[huse_spud]

I use either one layer of regular copier paper or two layers of aluminum foil.
the busrt disc works as a seal to prevent the fuel from leaking past the potato. this results in 250-300 yards per shot on my gun.

Cool, i've been trying to get members to make ice ammo, give that a try.

[rna_duelers]

I have used ice ammo,it flys eraticly but its still cool

I prolly get 50-100 yards more with my easter egg ice slugs (check those out in the ammo discussion)
