I also have 6 7.62x54R shells that I could reload but it would be hard to machine something for them with my tools

all I need now is a good 12 gauge tube

would mild steel work?

or do I need hardened stuff?

if i recall pressure on a 12 gauge is actually really low like at 12k psi so i would guess just black iron pipe would work

dont quote me on that tho

if unshure use whatever is safer

It all depends on how long you need it to work for

20 shots? Mild steel will work. More than that, you *will* get fucked

I personally hope not at all

Remember hardened steel is brittle

but considering the amount of that thing will be here for, I don't wanna have to go finding a strong another pipe for a shotgun

hmm

Use regular pipe

hmm, google is saying a Cr,Mo steel type

Just have interchangeable pipes

schedule 80 steel pipe is what you want i think. rated for a burst pressure of 14k psi

Or fit a 1 inch pipe over a 3/4 inch pipe and solder it together

All still has chromium and Molybdenum in it

yo kekno you're a fucking genius

Thanks

*braze

*weld

Either will work

Or weld

Soldering is easier

yea but thats meant for like water lines in a house

You can’t Solider steel dumb ass

not a shotgun barrel

Yes you can

I've done it before

It’s not a strong joint

I can't weld, I have a solder gun and there aren't going to be strong forces seperating the too

Doesn't matter, all it needs to do is keep them from sliding apart

Or just buy Schedule 80 pipe

/ steam pipe

btw what gauge would be the best?
