Rifling

Rifling, overall life, max pressure requirements, etc.

I'll give you $5 to test your theory. Post the video and I'll reimburse you.

please try shooting a bullet through that and post results after

They are only expensive if you are poor.

Are we getting raided again? I’m seeing some poor quality posts recently and this is one of them.

>Things are only expensive when you don't have money
Your brain must be so goddamn big to come to that groundbreaking conclusion.

It's designed for 1000 PSI
bullet is only 800

This is as good as a SIG........if you point it at him first.

>more complex than a slam fire shotgun
>less functional
But why

It's cool

Its about energy over time. Water ramps up and reaches 800 PSI. Gunpowder explodes within a fraction of a second and reaches its high PSI.

Test it, faggot

I might
Expect an epic thread if it explodes

So are slam fire shotguns.

Ok

It's been done. I've seen many a 13 year old on youtube with a homemade single shot .22 made from a length of brake line, a 2x4, and various bits.
Not saying it's safe or lethal, just that it's been shown to work.

You're missing the point here. No shit people cannot buy shit if they do not have the money. It's like if a woman were trying to reproduce without sperm.

Do you comprende?

The only reason these don't blow up is that they are oversized, so a lot of the pressure just blows by the bullet. You get air gun velocities out of them, if that.

>rifling
Can be done to a solid rod of steel, with archaic methods, using a drill/press
>pressure
>material resistances
Those are what different steels have been researched for, so if you can get yourself a rod of the steel you see fit, you can make a barrel.

This guy has more of an advanced setup but it works nontheless

oh shit really?
what should I use instead?

Test it. Make sure you record it when you do.

then do all that shit yourself and stop complaining

I'm not OP, I'm just here to prove that barrels are just another finished product

Have you considered getting a higher paying job? At my company no one but the floor workers gets paid under 100k.

I'm confident that if you had a factory made up of people doing that guy's method it would be more expensive and shittier than a modern barrel. I haven't even watched the video.
