Shotgun-9mm thing

That should feel rewarding Toby.

Seems to work right enough.

Minimal meat damage. FMJ or expanding?

115gr JHP Which I think is jacketed hollow point? There's a lead tip flat with copper jacket. Must shred off the copper inside cause there were cuts through the lungs liver heart

Yep.

Not sure what to use next but they are bloody loud. Want to make subs for it now

You could machine down the end of insert to thread and fit a small chamber on the end of the insert,with a fair bit of clearance on the projectile.

Thats not a bad idea cam. I was thinking a whole barrel in a new gun and making it so the extractor on the gun can pull the shell out as well

How much are pistol barrels?

Thinking of making a sleeve to go over the pistol barrel like a bushing or even a thread so it screws into in the out side will be like the bit I have that fits the shotgun but it will be rifled. Surely that'd be better then no rifling?

Is it rifled? any pics please

Garden gun?

Is it a 9mm Flobert?

dam thats pretty awesome :thumbsup:

@hamsav ?

That thing looks pretty neat but I'd rather a rifled 9mm luger

It looks like you have all the gear needed to make a semi auto sten style rifle,7round mag and it's a cat.

Last one I know of cost the guy not much more than the barrel to make

That'd be cool to have

Haha we've definitely got our fair share of "one's" around here

Thanks hamsav

Whats the "one" you speak of?

Keuano Reeves. He is the one.

Oh righto, nah no offence taken. I had no idea what you mean by "the one" still have no idea to be honest either

6 Inch bull barrel 9mm - For Sale - Auckland Pistol Club

that coat way too much. Hopefully a gunsmith will have a cut off or something laying around

What length do you want?

Toby
I have a 6-8" sako barrel chambered in 308win you can have for this project if...

1 You do your research yourself and find the max pressures of the relevant chamerings(12g and 308 win)
2 Convert pressure over area to to thrust against the action comparatively.
3 Post it up here for everyone to pick holes in.

It would require some work to make it work but nothing a bright young mind with access to a lathe couldn't sort;)

Alternatively I have the other two bits of 30cal rifled barrel:wtfsmilie::yaeh am not durnk:

Is 30cal the same as 9mm? I thought 9mm was bigger

I can't thread on a lathe I'd have to get someone else who can to do it. The teachers cant do it so I've never learnt which sucks

Unless you mean for a .308 insert which would be kick ass for subs aye. Will do the research and post it up here for everyone to pick holes in :)

PVC pipe any use to you Toby? I have some that I could spare. Ha ha ha ha

Yes a 308 insert,or perhaps a 30 pistol cal.
Do your lathes at work not have a lead screw?


Edit school

Whats a lead screw?

running for cover :)

No really the school has very basic equipment and the teacher is a wood work teacher. Kinda annoyes me but cant do shit about it

If you have a half decent lathe you'll be able to cut a thread on it. Just get a good lathe book and nut it out, tooling is usually the expensive bit if you don't have any, if you need anything like that done I have a mate here who has a lathe and mill setup at home and could do it.

So the highest of the highest I have found in my data is 11,300PSI-12G and 61,500PSI-.308

I dont have sub sonic loads for .308 so will have to wait until I get on the computer to have a look for that. Also don't know the other bit so will also wait till I get on the pc and google it

Well that will go well!:roll:

I hope subs are better. I don't think a full load is bad either as its in its own barrel if thats right?

Hint, work out the area of each case head.............................PSI stands for Pounds Per Square inch.

And the calculation Toby should be simple for a fellah like you. Just remember Big Ben Pies are Square.

Hopefully I've got this right

area for 12g - 0.6165"
"""""""".308-- 0.1750"

I can't do the litte 2 off my phone to show its sqaured

So thrust or pressure applied to the action for each is?

I googled and can't find a formula for that. Do you know one I can work off?

VC you are subtly becoming quite the physics teacher. Keep it up and Toby will thank you for it one day.
