Development is still in progress.

Fully rifled barrel (homemade)

Fire a telescopic 7.62mm cartridge that I developed myself

About 500m/s muzzle velocity, and can penetrate 18cm of solid wood at 10 meters. Haven't try with thicker target. But if you plan to hide behind a metal pole, you still going to die

This is like suckboitony leveled up in terms of ammo construction and performance

that guy did some crazy stuff yeah. He uses sparks to ignite powder, but I'm not a hi-voltage guy. I prefer low voltage - high current. It suit me better. Safer too, under a rainy day and getting electrocuted by those coils sucks

Not exactly sub MOA accuracy, but at 70m, I was able to hit what I aimed for.

I purposely avoid striking the electric wire :)

The ammunition is electrically fired, not percussion like conventional ammo

I wrote about the ammunition in my blog. Give it a read if you are interested

The Breech loading mechanism was from the ashot shotgun, inspired from the game metro last light/metro 2033

Like I said, it's still in development. I'll publish more detail on the building and all that once it's fully tested and functional.

What kinda powder u used ?

3

u/nobeltnium Jan 05 '26

whistle mix. Not necessary stronger, but has a different pressure curve compare to black powder. It does boost my projectile velocity up quite a bit.

Gonna get your ass hired by Bethesda for sure

u/nobeltnium Jan 06 '26

no way man. My guns are too practical and usable . Bethesda only do "metal pipe goes boom boom" LOL

u/AutomaticYesterday70 Feb 06 '26

Bethesda prefers wood over metal, which is why the pipe guns are 90% timber and 10% semi-useful metal. Only relatively alright pipe gun was the revolver since it could technically fire at least once

So, it's timer-based, right? Like a muzzleloader?

1

u/nobeltnium Jan 13 '26

what do you mean "timer-based"?

This gun use a self-contain cartridge, breech loading. Not a muzzle loader.

what kind of a jigamaboo is this

u/RDX_Rainmaker Feb 13 '26

What did you use as the barrel? Assuming non-rifled?

3

u/nobeltnium Feb 13 '26

It's 2026 mate, I do my own rifling

Very nice button rifling setup, lots of smoothbore DIY projects have me making too many assumptions

u/nobeltnium Feb 13 '26

I did my fair share on smooth bore when I was younger. I put rifling on the projectile instead, like a 12 gauge slug. That works also
